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 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

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).
