Si5330
2. Functional Description
2.3. Output Enable (OEB)
The Si5330 is a low-jitter, low-skew fanout buffer
optimized for high-performance PCB clock distribution
applications. The device produces four differential or
eight single-ended, low-jitter output clocks from a single
input clock. The input can accept either a single-ended
or a differential clock allowing the device to function as a
clock level translator.
The output enable (OEB) pin allows disabling or
enabling of the outputs clocks (CLK0-CLK3). The output
enable is logically controlled to ensure that no glitches
or runt pulses are generated at the output as shown in
Figure 3.
2.1. VDD and VDDO Supplies
The core VDD and output VDDO supplies have separate
and independent supply pins allowing the core supply to
operate at a different voltage than the I/O voltage levels.
The VDD supply powers the core functions of the device,
which operates from 1.8, 2.5, or 3.3 V. Using a lower
supply voltage helps minimize the device’s power
consumption. The VDDO supply pins are used to set the
output signal levels and must be set at a voltage level
compatible with the output signal format.
All outputs are enabled when the OEB pin is connected
to ground or below the VIL voltage for this pin.
Connecting the OEB pin to VDD or above the VIH level
will disable the outputs. Both VIL and VIH are specified
in Table 5. All outputs are forced to a logic “low” when
disabled. The OEB pin is 3.3 V tolerant.
2.2. Loss Of Signal Indicator (LOS)
2.4. Input Signals
The input is monitored for a valid clock signal using an
LOS circuit that monitors input clock edges and
declares an LOS condition when signal edges are not
detected over a 1 to 5 μs observation period. The LOS
pin is asserted “low” when activity on the input clock pin
is present. A “high” level on the LOS pin indicates a loss
of signal (LOS). The LOS pin must be pulled to VDD as
shown in Figure 2.
The Si5330 can accept single-ended and differential
input clocks. See “AN408: Termination Options for AnyFrequency, Any-Output Clock Generators and Clock
Buffers—Si5338, Si5334, Si5330” for details on
connecting a wide variety of signals to the Si5330
inputs.
Figure 3. OEB Glitchless Operation
2.5. Output Driver Formats
The Si5330 supports single-ended output formats of
CMOS, SSTL, and HSTL and differential formats of
LVDS, LVPECL, and HCSL. It is normally required that
the LVDS driver be dc-coupled to the 100 termination
at the receiver end. If your application requires an accoupled 100 load, contact the applications team for
advice. See AN408 for additional information on the
terminations for these driver types.
2.6. Input and Output Terminations
See AN408 for detailed information.
3. Ordering the Si5330
Figure 2. LOS Indicator with External Pull-Up
The Si5330 can be ordered to meet the requirements of
the most commonly-used input and output signal types,
such as CMOS, SSTL, HSTL, LVPECL, LVDS, and
HSCL. See Figure 1, “Si5330 Functional Block
Diagrams,” on page 2 and Table 11, “Order Numbers
and Device Functionality,” on page 14 for specific
ordering information.

All outputs are enabled when the OEB pin is connected
to ground or below the VIL voltage for this pin. Connecting the OEB pin to VDD or above the VIH level will disable the outputs. Both VIL and VIH are specified in
Table 5. All outputs are forced to a logic “low” when disabled. This pin is 3.3 V tolerant.
Supply
Output Clock Supply Voltage.
Supply voltage for CLK0A,B. Use a 0.1 μF bypass cap
as close as possible to this pin. If CLK2 is not used, this
pin must be tied to VDD (pin 7 and/or pin 24).

Supply
Core Supply Voltage.
The device operates from a 1.8, 2.5, or 3.3 V supply. A
0.1 μF bypass capacitor should be located very close to
this pin.
Supply
Ground Pad.
This is main ground connection for this device. It is
located at the bottom center of the package. Use as
many vias as possible to connect this pad to the main
ground plane. The device will not function as specified
unless this ground pad is properly connected to ground.

Notes:
General

4.
All dimensions shown are in millimeters (mm) unless otherwise noted.
Dimensioning and Tolerancing per ANSI Y14.5M-1994 specification.
This Land Pattern Design is based on the IPC-7351 guidelines.
Connect the center ground pad to a ground plane with no less than five vias to a ground plane that is no more than
20 mils below it. 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-020C specification for Small Body Components.
