(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
2.5V or 3.3V, В±10% operation.
