2.5V and 3.3V LVCMOS Clock Fanout Buffer

The MPC9443 is a 2.5V and 3.3V compatible 1:16 clock distribution buffer designed for low-voltage high-performance telecom, networking and computing applications. The device supports 3.3V, 2.5V and dual supply voltage (mixed-voltage) applications. The MPC9443 offers 16 low-skew outputs which are divided into 4 individually configurable banks. Each output bank can be individually supplied by 2.5V or 3.3V, individually set to run at 1X or 1/2X of the input clock frequency or be disabled (logic low output state). Two selectable LVPECL compatible inputs support differential clock distribution systems. In addition, one selectable LVCMOS input is provided for LVCMOS clock distribution systems. The MPC9443 is specified for the extended temperature range of –40 to +85°C.
