B9947 - 1:9 Clock Distribution Buffer

Description

The B9947 is a low-voltage clock distribution buffer with the capability to select one of two LVCMOS/LVTTL compatible clock inputs.

The two clock sources can be used to provide for a test clock as well as the primary system clock.

All other control inputs are LVCMOS/LVTTL compatible.
