Description
The Si5334 is a high performance, low jitter clock generator capable of
synthesizing any frequency on each of the device's four differential output
clocks. The device accepts an external reference clock or crystal and generates
four differential clock outputs, each of which is independently configurable to
any frequency up to 350 MHz and select frequencies to 710 MHz. Using
Skyworks Solutions' patented MultiSynth technology, each output clock is
generated with very low jitter and zero ppm frequency error. To provide
additional design flexibility, each output clock is independently configurable to
support any signal format and reference voltage. The Si5334 provides low jitter
frequency synthesis with outstanding frequency flexibility in a space-saving
4 x 4 mm QFN package. The device configuration is factory or field programmed
and, upon power up, the device will begin operation in the predefined
configuration without user intervention. The device supports operation from a
1.8, 2.5, or 3.3 V core supply.

Notes:
1. All jitter measurements apply for LVDS/HCSL/LVPECL output format with a low noise differential input clock and are
made with an Agilent 90804 oscilloscope. All RJ measurements use RJ/DJ separation.
2. For best jitter performance, keep the single ended clock input slew rates at Pins 3 and 4 more than 1.0 V/ns and the
differential clock input slew rates more than 0.3 V/ns.
3. All jitter data in this table is based upon all output formats being differential. When single-ended outputs are used, there
is the potential that the output jitter may increase due to the nature of single-ended outputs. If your configuration
implements any single-ended output and any output is required to have jitter less than 3 ps rms, contact Skyworks
Solutions for support to validate your configuration and ensure the best jitter performance. In many configurations,
CMOS outputs have little to no effect upon jitter.

Figure 1. Si5334 Block Diagram
The Si5334 is a high-performance, low-jitter clock
generator capable of synthesizing any frequency on
each of the device's four differential output clocks. The
device accepts an external crystal from 8 to 30 MHz or
an input clock ranging from 5 to 710 MHz. Each output
is independently factory-programmable to any
frequency up to Fvco/8 (max of 350 MHz) and select
frequencies to 710 MHz.
The Si5334 fractional-N PLL, comprised of a phase
detector, charge pump, loop filter, VCO, and dividers, is
fully integrated on chip to simplify design. Using
Skyworks Solutions' patented MultiSynth technology,
each output clock is generated with low jitter and zero
ppm frequency error. The device has four MultiSynth
output dividers to provide non-integer frequency
synthesis on every differential output clock.
The Si5334 output driver is highly flexible. The signal
format of each output clock can be user-specified to
support LVPECL, LVDS, HCSL, CMOS, HSTL, or SSTL.
Each output clock has its own supply voltage to allow for
the utmost flexibility in mixed supply operations. The
core of the Si5334 has its own supply voltage that can
be 1.8, 2.5, or 3.3 V.
The Si5334 supports an optional zero delay mode of
operation. In this mode, one of the device output clocks
is fed back to the FDBK/FDBKB clock input pins to
implement the PLL feedback path and nullify the phase
difference between the reference input and the output
clocks.
The Si5334D/E/F has a pin-controlled phase
increment/decrement feature that allows the user to
adjust the phase of each output clock in relation to the
other output clocks. The phase of each differential
output clock can be set to an accuracy of 20 ps over a
range of ±45 ns. This feature is available over the 0.16
to Fvco/8 MHz frequency range at a maximum rate of
phase change of 1.5 MHz.
The Si5334G/H/J has a pin-controlled frequency
increment/decrement feature that allows the user to
change frequency in steps as small as 1 ppm of the
initial frequency to as large as possible as long as the
frequency at the output of the MultiSynth stays within
the range of 5 MHz to Fvco/8 MHz. This feature is
available on CLK0A/B only. The frequency step is
glitchless. This feature is useful in applications that
require a variable clock frequency. It can also be used in
frequency margining applications to margin test system
clocks during design/verification/test or manufacturing
test applications.
For EMI reduction, the Si5334K/L/M supports PCI
Express 2.0 compliant spread spectrum on all output
clocks that are 100 MHz.

Si5334
The Si5334 is pin-controlled. No I2C interface is
provided. The LOLLOS output pin indicates the lock
condition of the PLL. An output enable input pin is
available on the Si5334A/B/C which affects all the
programmed clock outputs. All device specifications are
guaranteed across these three core supply voltages.
Packaged in a ROHS-6, Pb-free 4x4 mm QFN package,
the device supports the industrial temperature range of
–40 to +85 °C.
After core power is applied, the Si5334 downloads the
factory-programmed NVM into RAM and begins
operation.
2.2. Crystal/Clock Input
The device can be driven from either a low frequency
fundamental mode crystal (8–30 MHz) or an external
reference clock (5–710 MHz). The crystal is connected
across pins IN1 and IN2.
The PCB traces between the crystal and the device
must be kept very short to minimize stray capacitance.
To ensure maximum compatibility with crystals from
multiple vendors, the internal crystal oscillator provides
adaptive crystal drive strength based upon the crystal
frequency.
The crystal load capacitors are placed on-chip to reduce
external component count. If a crystal with a load
capacitance outside the range specified in Tables 2, 3,
and 12 is supplied to the device, it will result in a slight
ppm error in the device clock output frequencies. This
error can be compensated for by a small change in the
input to output multiplication ratio.
If a reference clock is used, the device accepts a singleended input reference on IN3 or a differential LVPECL,
LVDS, or HCSL source on IN1 and IN2. The input at IN3
can accept an input frequency up to 200 MHz. The
signal applied at IN3 should be dc-coupled because
internally this signal is ac-coupled to the receive input. A
single-ended reference clock up to 350 MHz can be accoupled to IN1. A differential reference clock, such as
LVPECL, LVDS or HCSL, is input on IN1,2 for
frequencies up to 700 MHz. The differential input to
IN1,2 requires 0.1 µF ac coupling caps to be located
near the device and a 100 termination resistor to be
located between these caps and the transmission line
going back to the differential driver. See “AN408:
Termination Options for Any-Frequency, Any-Output
Clock Generators and Clock Buffers” for more
information on connecting input signals to IN1,2,3.
This application note can be downloaded from
https://www.skyworksinc.com/en/Products/Timing.
2.3. Zero Delay Mode
A clock that is input to the Si5334 will have an
unspecified amount of delay from the input pins to the
output pins. The zero delay mode can be used to
reduce the delay through the Si5334 to typically less
than 100 ps. This is accomplished by feeding back the
CLK3 output to either IN4 or IN5,6. Using CLK3 allows
for an easy PCB route of this signal back to the input.
The R3 divider must be set to 1 when using feedback
from CLK3 to implement the zero delay mode. All output
clocks that are required to have zero delay must also
have their Rn divider set to 1. A single-ended signal up
to 200 MHz from CLK3 can be input to IN4. A singleended signal up to 350 MHz from CLK3 can be input to
IN5 using the technique shown in AN408. A differential
signal up to 710 MHz from CLK3a,b must be input to
IN5,IN6.
The IN4 input is electrically the same as IN3 described
above. The IN5,IN6 inputs are electrically the same as
the IN1,IN2 inputs described above. See AN408 for
additional information on signal connections for the zero
delay mode.
2.4. Breakthrough MultiSynth Technology
Next-generation timing IC architectures require a wide
range of frequencies which are often non-integer
related. Traditional clock architectures address this by
using multiple single PLL ICs, often at the expense of
BOM complexity and power. The Si5334 and Si5338
use patented MultiSynth technology to dramatically
simplify timing architectures by integrating the
frequency synthesis capability of 4 Phase-Locked
Loops (PLLs) in a single device, greatly minimizing size
and power requirements versus traditional solutions.
Based on a fractional-N PLL, the heart of the
architecture is a low phase noise, high frequency VCO.
The VCO supplies a high frequency output clock to the
MultiSynth block on each of the four independent output
paths. Each MultiSynth operates as a high speed
fractional divider with Skyworks Solutions' proprietary
phase error correction to divide down the VCO clock to
the required output frequency with very low jitter.
The first stage of the MultiSynth architecture is a
fractional-N divider which switches seamlessly between
the two closest integer divider values to produce the
exact output clock frequency with 0 ppm error. To
eliminate phase error generated by this process,
MultiSynth calculates the relative phase difference
between the clock produced by the fractional-N divider
and the desired output clock and dynamically adjusts
the phase to match the ideal clock waveform. This novel
approach makes it possible to generate any output
clock frequency without sacrificing jitter performance.

Si 5334
2.5. Output Driver
Based on this architecture, the output of each
MultiSynth can produce any frequency from 5 to Fvco/8
MHz. To support higher frequency operation, the
MultiSynth divider can be bypassed. In bypass mode
integer divide ratios of 4 and 6 are supported, which
allows for output frequencies of Fvco/4 and Fvco/6 MHz
which translates to 367–473.3 MHz and 550–710 MHz
respectively. Because each MultiSynth uses the same
VCO output there are output frequency limitations when
output frequencies greater than Fvco/8 are desired.
For example, if 375 MHz is needed at the output of
MultiSynth0, the VCO frequency would need to be
2.25 GHz. Now, all the other MultiSynths can produce
any frequency from 5 MHz up to a maximum frequency
of 2250/8 = 281.25 MHz. MultiSynth1,2,3 could also
produce Fvco/4 = 562.5 MHz or Fvco/6 = 375 MHz.
Only two unique frequencies above Fvco/8 can be
output: Fvco/6 and Fvco/4.
There are four clock output channels on the Si5334
(CLK0,CLK1,CLK2,CLK3) with two signal outputs per
channel. Each channel may be programmed to be a
differential driver or a dual single ended driver. If a
channel is factory-programmed to be single ended, then
the two outputs for that channel can be factoryprogrammed to be in-phase or out-of-phase. Si5334
output drivers can be configured as single ended
CMOS, SSTL, HSTL or differential LVPECL, LVDS, and
HCSL formats.
The supply voltage requirement for each driver format is
selectable as shown in Table 14. All unused clock
output channels must have their respective VDD0x
supply voltage connected to pin 7 and 24 VDD.

Si5334
An OEB pin is provided to enable/disable the output
clocks. When OEB = 0, all outputs that have been
factory programmed will be on. When OEB = 1, all clock
outputs that have been factory programmed will be off
and held to a low level.
2.6. Output Clock Initial Phase Offset
Each CLKn output of the Si5334 can have its own
unique initial phase offset over a range of +- 45 ns with
an accuracy of 20 ps. When the respective R divider is
not set to 1, this function is not supported.
2.7. Output Clock Phase Increment and
Decrement
The Si5334D/E/F has a pin-controlled phase
increment/decrement feature that allows the user to
adjust the phase of 1 or more output clocks via pin
control. Since their is only 1 pin for increment and 1 pin
for decrement, each output clock channel needs to be
enabled or disabled for this feature. In addition, the
magnitude of the phase step must be set for each clock
output channel. The phase adjustment accuracy is
20 ps over a range of ±45 ns, and the phase transition is
glitchless. This feature is not available on any clock
output that has Spread Spectrum enabled. The
maximum clock output frequency supported in this
mode of operation is Fvco/8, where Fvco is the
frequency of the device's internal voltage controlled
oscillator for the configured frequency plan. The phase
can be changed at a maximum rate of 1.5 MHz. In order
to increment or decrement phase it is necessary to input
a positive pulse of >100ns followed by a low of >100 ns.
Since this feature uses pins 3 and 4, the reference clock
must be input at pins 1 and 2 or the crystal used across
these pins. Once a Si5334/D/E/F is factoryprogrammed,
the
phase
increment/decrement
parameters cannot be changed. If one desires to
subsequently change the phase increment/decrement
parameters on a factory-programmed part, the Si5338
clock generator must be used.
If a phase decrement causes a single MultiSynth clock
period to be less than 8/Fvco, all clock outputs may turn
off for up to 10 clock periods and then come back on
with the phase setting before the illegal decrement.
2.8. Output Clock Frequency Increment
and Decrement
The Si5334G/H/J has a pin-controlled frequency
increment/decrement feature that allows the user to
adjust the frequency at the output of MultiSynth0 only.
MultiSynth0 can be connected to any or all of the four
output clock buffers with the muxes shown in the
" Functional Block Diagram" on page 2. If frequency
increment and decrement is required on the other clock
outputs the Si5338 should be used. The magnitude of a
single frequency step must be factory-programmed.
Spread Spectrum and frequency increment/decrement
cannot both be active on the same clock output. There
is a single pin to control the frequency increment and a
single pin to control the frequency decrement. The
frequency increment or decrement step size can be
factory-programmed from as low as 1 ppm of the initial
frequency to a maximum that keeps the output of the
MultiSynth within the limits of 5 MHz to Fvco/8. If a
frequency increment causes the MultiSynth0 output
frequency to go above Fvco/8, then all output clocks
may turn off for up to 10 clock cycles and then come
back on at the frequency before the increment. If the
output frequency needs to go below 5 MHz, refer to
"2.9. R Divider Considerations" on page 17 for further
information. The frequency transition is glitchless. The
frequency can be changed at a maximum rate of
1.5 MHz. In order to increment or decrement frequency
it is necessary to input a positive pulse of >100 ns
followed by a low of > 100 ns. Since this feature uses
pins 3 and 4, the reference clock must be input at pins 1
and 2 or the crystal used across these pins. Once a
Si5334/G/H/J is factory-programmed, the frequency
increment/decrement parameters cannot be changed. If
one desires to subsequently change the frequency
increment/decrement parameters on a programmed
part, the Si5338 clock generator must be used.
2.9. R Divider Considerations
When the requested output frequency of a channel is
below 5 MHz, the Rn (n = 0,1,2,3) divider will
automatically be set and enabled. When the Rn divider
is active the step size range of the frequency increment
and decrement function will decrease by the Rn divide
ratio. The Rn divider can be set to {1, 2, 4, 8, 16, 32}.
Non-unity settings of R0 will affect the Finc/Fdec step
size at the MultiSynth0 output. For example, if the
MultiSynth0 output step size is 2.56 MHz and R0 = 8,
the step size at the output of R0 will be 2.56 MHz
divided by 8 = .32 MHz. When the Rn divider is set to
non-unity, the initial phase of the CLKn output with
respect to other CLKn outputs is not guaranteed.

2.11. Device Reset
To reset the device, a power cycle must be performed.
Output Clock Frequency
Modulation Rate
Time
Figure 3. Spread Spectrum Triangle Waveform
To reduce the electromagnetic interference (EMI), the
Si5334K/L/M supports PCI Express compliant spread
spectrum on all outputs that are 100 MHz. If CLK0 has
spread spectrum enabled, then the Finc/Fdec function
is not available on CLK0. Spread spectrum modulation
spreads the energy across many frequencies to reduce
the EMI across a narrow range of frequencies.
The modulation rate is the time required to transition
from the maximum spread spectrum frequency to the
minimum spread spectrum frequency and then back to
the maximum frequency as shown in Figure 3.
The Si5334K/L/M supports 0.5% downspread at a 30–
33 kHz rate with a clock frequency of 100 MHz in
compliance with the PCI Express standard. When pin
12 (SSPB) is low the factory-programmed clock outputs
will have spread spectrum turned on.
2.12. LOSLOL Pin
When either a Loss of Lock (LOL) or Loss of Signal
(LOS) condition occurs, the LOSLOL pin will assert.
The LOS condition occurs when there is no input clock
input to the Si5334. The loss of lock algorithm works by
continuously monitoring the frequency difference
between the two inputs of the phase frequency detector.
When this frequency difference is greater than
1000 ppm, a loss of lock condition is declared. Note that
the VCO will track the input clock frequency for up to
~50000 ppm, which will keep the inputs to the phase
frequency detector at the same frequency until the PLL
comes out of lock. When a clock input is removed, the
LOSLOL pin will assert, and the clock outputs may drift
up to 5%. When the input clock with an appropriate
frequency is re-applied, the PLL will again lock.
2.13. Power-Up
Upon powerup, the device performs an internal selfcalibration before operation to optimize loop parameters
and jitter performance. While the self-calibration is
being performed, the device VCO is being internally
controlled by the self-calibration state machine and the
LOL alarm is masked. The output clocks appear after
the device finishes self calibration.
2.14. Factory Programming Options

Notes
General:
1. All dimensions shown are in millimeters (mm) unless otherwise noted.
2. Dimensioning and Tolerancing per ANSI Y14.5M-1994 specification.
3. This Land Pattern Design is based on the IPC-7351 guidelines.
4. Connect the center ground pad to a ground plane with no less than five vias. These 5 vias should have a length of no
more than 20 mils to the ground plane. Via drill size should be no smaller than 10 mils. A longer distance to the ground
plane is allowed if more vias are used to keep the inductance from increasing.
Solder Mask Design:
5. All metal pads are to be non-solder mask defined (NSMD). Clearance between the solder mask and the metal pad is to
be 60 µm minimum, all the way around the pad.
Stencil Design:
6. A stainless steel, laser-cut and electro-polished stencil with trapezoidal walls should be used to assure good solder
paste release.
7. The stencil thickness should be 0.125 mm (5 mils).
8. The ratio of stencil aperture to land pad size should be 1:1 for all perimeter pins.
9. A 2x2 array of 1.0 mm square openings on 1.25 mm pitch should be used for the center ground pad.
Card Assembly:
10. A No-Clean, Type-3 solder paste is recommended.
11. The recommended card reflow profile is per the JEDEC/IPC J-STD-020 specification for Small Body Components.
