True Drop-in Solution for Zero Delay Buffer,

ASM5P2305A / 09A

Functional Description

PCS3P622Z05/09 is a versatile, 3.3V Zero-delay buffer

designed to distribute low frequency Timing-Safe™ clocks

with Peak EMI reduction. PCS3P622Z05 is an eight-pin

version, accepts one reference input and drives out five

low-skew Timing-Safe™ clocks. PCS3P622Z09 accepts

one reference input and drives out nine low-skew Timing-

Safe™clocks.

PCS3P622Z05/09 has a DLY_CTRL for adjusting the

Input-Output clock delay, depending upon the value of

capacitor connected at this pin to GND.

PCS3P622Z05/09 operates from a 3.3V supply and is

available in two different packages, as shown in the

ordering information table, over commercial and Industrial

temperature range.

Application

PCS3P622Z05/09 is targeted for use in Displays and

memory interface systems.
