Product Description
The ASM2P2351AH 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 ASM2P2351AH operates at nominal 3.3V Supply
Voltage.
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 ASM2P2351AH is characterized for operation
from 0

C to 70
