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.
