table
for details.
ASM3P622S00E has a CLKOUT for adjusting the Input-
Output clock delay, depending upon the value of capacitor
connected at this pin to GND.
ASM3P622S00B/E 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.
Functional Description
Application
ASM3P622S00B/E is a versatile, 3.3V Zero-delay buffer
designed to distribute low frequency Timing-Safe™ clocks
with Peak EMI reduction. ASM3P622S00B is an eight-pin
version, accepts one reference input and drives out one
low-skew Timing-Safe™ clock. ASM3P622S00E accepts
ASM3P622S00B/E is targeted for use in Displays and
memory interface systems.
