DESCRIPTION

The PL123-05/-09 (-05H/-09H for High Drive) are high

performance, low skew, low jitter zero delay buffers

designed to distribute high speed clocks. They have

one (PL123-05) or two (PL123-09) low-skew output

banks, of 4 outputs each, that are synchronized with

the input. The PL123-09 allows control of the banks of

outputs by using the S1 and S2 inputs as shown in the

Selector Definition table on page 2.

The synchronization is established via CLKOUT feed

back to the input of the PLL. Since the skew between

the input and output is less than

100ps, the device

acts as a zero delay buffer. The input output propaga-

tion delay can be advanced or delayed by adjusting the

load on the CLKOUT pin.

These parts are not intended for 5V input-tolerant ap-

plications.
