This low-skew, low-jitter device is capable of accepting a
high-speed (e.g., 622MHz or higher) CML, LVPECL, LVDS
or HSTL clock input signal and dividing down the frequency
using a programmable divider to create a lower speed
version of the input clock. Available divider ratios are 2, 4, 8
and 16, or straight pass-through.
The differential input buffer has a unique internal
termination design that allows access to the termination
network through a V
T pin. This feature allows the device to
easily interface to different logic standards. A V
REF-AC
reference is included for AC-coupled applications.
The /RESET input asynchronously resets the divider. In
the pass-through function (divide by 1) the /RESET
synchronously enables or disables the outputs on the next
falling edge of IN (rising edge of /IN).
