General Description
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 ratio to create a
frequency-locked, lower speed version of the input clock.
Available divider ratios are 2, 4, 8 and 16, or straight pass-
through. In a typical 622MHz clock system this would
provide availability of 311MHz, 155MHz, 77MHz, or
38MHz auxiliary clock components.
The differential input buffer has a unique internal
termination design that allows access to the termination
network through a VT pin. This feature allows the device to
easily interface to different logic standards. A VREF-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 /N).
