Functional Description
ASM3P623S00B/E is a versatile, 3.3V Zero-delay buffer
designed to distribute Timing-Safe™ clocks with Peak EMI
reduction. ASM3P623S00B is an eight-pin version, accepts
one reference input and drives out one low-skew Timing-

Safe™ clock. ASM3P623S00E accepts one reference input
and drives out eight low-skew Timing-Safe™clocks.
ASM3P623S00B/E has an SS% that selects 2 different
Deviation and associated Input-Output Skew (T_SKEW). Refer
Spread Spectrum Control and Input-Output Skew table
for details.
ASM3P623S00E has a CLKOUT for adjusting the Input-
Output clock delay, depending upon the value of capacitor
connected at this pin to GND.
ASM3P623S00B/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.
Application
ASM3P623S00B/E is targeted for use in Displays and
memory interface systems.
