(Preliminary) PL123E-05 Low Skew Zero Delay Buffer
FEATURES DESCRIPTION п‚ п‚ п‚ п‚ The PL123E-05 (-05H for High Drive) is a high performance, low skew, low jitter zero delay buffer d esigned
to distribute high speed clocks. It has five low-skew
outputs that are synchronized with the input. The sy nchronization is established via CLKOUT feed back to
the input of the PLL. Since the skew between the input
and output is less than п‚±100ps, the device acts as a
zero delay buffer. The input output propagation delay
can be advanced or delayed by adjusting the load on
the CLKOUT pin. п‚ п‚ Frequency Range 10MHz to 220MHz
Zero input -output delay.
Low output-to-output skew.
Optional Drive Strength:
Standard (8mA) PL123E-05

PL123E-09 (Preliminary) Low Skew Zero Delay Buffer
FEATURES DESCRIPTION п‚ п‚ п‚ п‚ The PL123E-09 (-09H for High Drive) is a high performance, low skew, low jitter zero delay buffer d esigned
to distribute high speed clocks. It has two low-skew
output banks, of 4 outputs each, that are synchronized
with the input. Control of the two banks o f outputs is
achieved by using the S1 and S2 inputs as shown in
the Selector Definition table on page 2. п‚ п‚ Frequency Range 10MHz to 220MHz
Zero input -output delay.

2.5V or 3.3V, В±10% operation.
Available in 16-Pin SOP or TSSOP packages 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 п‚±100ps, the device
acts as a zero delay buffer. The input output propagation delay can be advanced or delayed by adjusting the
load on the CLKOUT pin.

PL123S-05/-09
Spread-Compatible Low Skew Zero Delay Buffer
FEATURES DESCRIPTION п‚ п‚ The PL123S-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 (PL123S-05) or two (PL123S-09) low-skew output
banks, of 4 outputs each, that are synchronized with
the input. The PL123S-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. п‚ п‚ п‚ п‚ п‚ п‚ Frequency Range 10MHz to 134 MHz
Output Options:
o 5 outputs PL123S-05
o 9 outputs PL123S-09
Zero input -output delay
