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. The nine outputs are 3.3V LVCMOS or LVTTL compatible and can drive two series terminated 50Ω transmission lines.
