841608
FemtoClock® Crystal-to-HCSL
Clock Generator
Datasheet
General Description
Features
The 841608 is an optimized PCIe and sRIO clock generator. The
device uses a 25MHz parallel crystal to generate 100MHz and
125MHz clock signals, replacing solutions requiring multiple
oscillator and fanout buffer solutions. The device has excellent
phase jitter (< 1ps rms) suitable to clock components requiring
precise and low-jitter PCIe or sRIO or both clock signals. Designed
for telecom, networking and industrial applications, the 841608 can
also drive the high-speed sRIO and PCIe SerDes clock inputs of
communication processors, DSPs, switches and bridges.

Recommendations for Unused Input and Output Pins
Inputs:
Outputs:
Crystal Inputs
HCSL Outputs
For applications not requiring the use of the crystal oscillator input,
both XTAL_IN and XTAL_OUT can be left floating. Though not
required, but for additional protection, a 1k resistor can be tied from
XTAL_IN to ground.
All unused HCSL outputs can be left floating. We recommend that
there is no trace attached. Both sides of the differential output pair
should either be left floating or terminated.
LVCMOS Control Pins
All control pins have internal pulldowns; additional resistance is not
required but can be added for additional protection. A 1k resistor
can be used.
REF_IN Input
For applications not requiring the use of the reference clock, it can be
left floating. Though not required, but for additional protection, a 1k
resistor can be tied from the REF_IN to ground.
Power Supply Filtering Technique
As in any high speed analog circuitry, the power supply pins
are vulnerable to random noise. To achieve optimum jitter
performance, power supply isolation is required. The 841608
provides separate power supplies to isolate any high switching noise from the outputs to the internal PLL. VDD and VDDA
should be individually connected to the power supply plane
through vias, and 0.01µF bypass capacitors should be used
for each pin. Figure 1 illustrates this for a generic VDD pin and
also shows that VDDA requires that an additional 10 resistor
along with a 10µF bypass capacitor be connected to the
VDDA pin.

Crystal Input Interface
The 841608 has been characterized with 18pF parallel resonant
crystals. The capacitor values shown in Figure 2 below were

LVCMOS to XTAL Interface
The XTAL_IN input can accept a single-ended LVCMOS signal
through an AC coupler capacitor. A general interface diagram is
shown in Figure 3. The XTAL_OUT pin can be left floating. The input
edge rate can be as slow as 10ns. For LVCMOS inputs, it is
recommended that the amplitude be reduced from full swing to half
swing in order to prevent signal interference with the power rail and
to reduce noise. This configuration requires that the output
VDD
impedance of the driver (Ro) plus the series resistance (Rs) equals
the transmission line impedance. In addition, matched termination at
the crystal input will attenuate the signal in half. This can be done in
one of two ways. First, R1 and R2 in parallel should equal the
transmission line impedance. For most 50 applications, R1 and R2
can be 100. This can also be accomplished by removing R1 and
making R2 50.

VFQFPN EPAD Thermal Release Path
In order to maximize both the removal of heat from the package and
the electrical performance, a land pattern must be incorporated on
the Printed Circuit Board (PCB) within the footprint of the package
corresponding to the exposed metal pad or exposed heat slug on the
package, as shown in Figure 5. The solderable area on the PCB, as
defined by the solder mask, should be at least the same size/shape
as the exposed pad/slug area on the package to maximize the
thermal/electrical performance. Sufficient clearance should be
designed on the PCB between the outer edges of the land pattern
and the inner edges of pad pattern for the leads to avoid any shorts.
and dependent upon the package power dissipation as well as
electrical conductivity requirements. Thus, thermal and electrical
analysis and/or testing are recommended to determine the minimum
number needed. Maximum thermal and electrical performance is
achieved when an array of vias is incorporated in the land pattern. It
is recommended to use as many vias connected to ground as
possible. It is also recommended that the via diameter should be 12
to 13mils (0.30 to 0.33mm) with 1oz copper via barrel plating. This is
desirable to avoid any solder wicking inside the via during the
soldering process which may result in voids in solder between the
exposed pad/slug and the thermal land. Precautions should be taken
to eliminate any solder voids between the exposed heat slug and the
land pattern. Note: These recommendations are to be used as a
guideline only. For further information, please refer to the Application
Note on the Surface Mount Assembly of Amkor’s Thermally/
Electrically Enhance Leadframe Base Package, Amkor Technology.
While the land pattern on the PCB provides a means of heat transfer
and electrical grounding from the package to the board through a
solder joint, thermal vias are necessary to effectively conduct from
the surface of the PCB to the ground plane(s). The land pattern must
be connected to ground through these vias. The vias act as “heat
pipes”. The number of vias (i.e. “heat pipes”) are application specific

Schematic Example
Figure 6 shows an example of 841608 application schematic. In this
example, the device is operated at VDD = 3.3V. The 18pF parallel
resonant 25MHz crystal is used. The C1 = 27pF and C2 = 27pF are
recommended for frequency accuracy. For different board layout, the
C1 and C2 may be slightly adjusted for optimizing frequency
accuracy. Two examples of HCSL terminations are shown in this
schematic. The decoupling capacitors should be located as close as
possible to the power pin.

Power Considerations
This section provides information on power dissipation and junction temperature for the 841608
Equations and example calculations are also provided.
1.
Power Dissipation.
The total power dissipation for the 841608 is the sum of the core power plus the analog power plus the power dissipation in the load(s).
The following is the power dissipation for VDD = 3.3V + 5% = 3.465V, which gives worst case results.
NOTE: Please refer to Section 3 for details on calculating power dissipation in the load.
•
Power (core)MAX = VDD_MAX * (IDD_MAX + IDDA_MAX) = 3.465V * (87mA + 15mA) = 353.43mW
•
Power (outputs)MAX = 44.5mW/Loaded Output pair
If all outputs are loaded, the total power is 8 * 44.5mW = 356mW
Total Power_MAX = (3.465V, with all outputs switching) = 353.43mW + 356mW = 709.43mW
2. Junction Temperature.
Junction temperature, Tj, is the temperature at the junction of the bond wire and bond pad, and directly affects the reliability of the device. The
maximum recommended junction temperature for devices is 125°C.
The equation for Tj is as follows: Tj = JA * Pd_total + TA
Tj = Junction Temperature
JA = Junction-to-Ambient Thermal Resistance
Pd_total = Total Device Power Dissipation (example calculation is in section 1 above)
TA = Ambient Temperature
In order to calculate junction temperature, the appropriate junction-to-ambient thermal resistance JA must be used. Assuming no air flow and
a multi-layer board, the appropriate value is 37°C/W per Table 7 below.
Therefore, Tj for an ambient temperature of 85°C with all outputs switching is:
85°C + 0.709W * 37°C/W = 111.2°C. This is well below the limit of 125°C.
This calculation is only an example. Tj will obviously vary depending on the number of loaded outputs, supply voltage, air flow and the type of
board (multi-layer).
Table 7. Thermal Resistance JA for 32-Pin VFQFPN, Forced Convection

3. Calculations and Equations.
The purpose of this section is to calculate power dissipation on the IC per HCSL output pair.
HCSL output driver circuit and termination are shown in Figure 7.

Figure 7. HCSL Driver Circuit and Termination
HCSL is a current steering output which sources a maximum of 17mA of current per output. To calculate worst case on-chip power dissipation,
use the following equations which assume a 50 load to ground.
The highest power dissipation occurs when VDD is HIGH.
Power
= (VDD_HIGH – VOUT) * IOUT, since VOUT – IOUT * RL
= (VDD_HIGH – IOUT * RL) * IOUT
= (3.465V – 17mA * 50) * 17mA
Total Power Dissipation per output pair = 44.5mW
