The PL133-27 is an advanced fanout buffer design for
high performance, low-power, small form-factor
applications. The PL133-27 accepts a reference
clock input of 1MHz to 150MHz and produces two
outputs of the same frequency. Reference clock
inputs may be LVCMOS or sine-wave signals (the
inputs are internally AC-coupled). PL133-27 is
designed to fit in a small 2 x 1.3 x 0.6mm DFN
package, and offers the best phase noise and jitter
performance and lowest power consumption of any
comparable IC.

LAYOUT RECOMMENDATIONS
The following guidelines are to assist you with a performance optimized PCB design:
Signal Integrity and Termination Considerations
Decoupling and Power Supply Considerations
- Keep traces short!
- Place decoupling capacitors as close as possible to
the V DD pin(s) to limit noise from the power supply
- Trace = Inductor. With a capacitive load this equals
ringing!
- Long trace = Transmission Line. Without proper
termination this will cause reflections (looks like ringing).
- Design long traces as “striplines” or “microstrips” with
defined impedance.
- Match trace at one side to avoid reflections bouncing
back and forth.
- Multiple V DD pins should be decoupled separately
for best performance.
- Addition of a ferrite bead in series with V DD can
help prevent noise from other board sources
- Value of decoupling capacitor is frequency
dependant. Typical values to use are 0.1F for
designs using crystals < 50MHz and 0.01F for
designs using crystals > 50MHz.

When a buffer is used to pass a signal then the buffer will add a little bit of its own noise. The phase noise on the
output of the buffer will be a little bit more than the phase noise in the input signal. To quantify the noise addition in
the buffer we compare the Phase Jitter numbers from the input and the output. The difference is called "Additive
Phase Jitter". The formula for the Additive Phase Jitter is as follows:
2
Additive Phase Jitter = (Output Phase Jitter) - (Input Phase Jitter)
