description
The CDC2351 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. Each output has an internal series damping resistor to improve signal integrity at the load. The CDC2351
operates at nominal 3.3-V V
.
CC
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.
The CDC2351 is characterized for operation from 0°C to 70°C. The CDC2351Q is characterized for operation
over the full automotive temperature range of –40°C to 125°C.
