DESCRIPTION

The CDC351 is a high-performance clock-driver circuit that distributes one input (A) to ten outputs (Y) with minimum

skew for clock distribution. The output-enable (OE) input disables the outputs to a high-impedance state. The

CDC351 operates at nominal 3.3-V VCC.

The propagation delays are adjusted at the factory using the P0 and P1 pins. The factory adjustments ensure that the

part-to-part skew is minimized and is kept within a specified window. Pins P0 and P1 are not intended for customer

use and should be connected to GND.
