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.
