DESCRIPTION
The PL602-XX is the smallest, high performance, lowest power differential output clock IC available for HCSL
timing applications. PL602-XX offers -130dBc at 10kHz offset at 100MHz, with a very low jitter
(2 ps TIE RMS), making it ideal for HCSL applications requiring small size and low power.

PCB LAYOUT CONSIDERATIONS FOR PERFORMANCE OPTIMIZATION
The following guidelines are to assist you with a performance optimized PCB design:
- Keep all the PCB traces to PL602-XX as short as
possible, as well as keeping all other traces as far away
from it as possible.
- Place the crystal as close as possible to both crystal
pins of the device. This will reduce the cross-talk
between the crystal and the other signals.
- Separate crystal pin traces from the other signals on the
PCB, but allow ample distance between the two crystal
pin traces.
- Place a 0.01µF~0.1µF decoupling capacitor between
VDD and GND, on the component side of the PCB,
close to the VDD pin. It is not recommended to place
this component on the backside of the PCB.
- It is highly recommended to keep the VDD and GND
traces as short as possible.
- When connecting long traces (> 1 inch) to a CMOS
output, it is important to design the traces as a
transmission line or ‘stripline’, to avoid reflections or
ringing. In this case, the CMOS output needs to be
matched to the trace impedance. Usually ‘striplines’ are
designed for 50Ω impedance and CMOS outputs
usually have lower than 50Ω impedance so matching
can be achieved by adding a resistor in series with the
CMOS output pin to the ‘stripline’ trace.
