2.5V, 3.3V LVCMOS CLOCK FANOUT BUFFER

clock distribution buffer designed for low-voltage high-performance telecom, networking

and computing applications. The device supports 3.3 V, 2.5 V 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

2.5 V or 3.3 V, 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.

Functional Description

signals are generated and retimed on-chip to ensure minimal skew between the four

output banks.

the MPC9443 supports single-ended LVCMOS clock distribution systems. Each of the four output banks can be individually supplied by

2.5 V or 3.3 V, supporting mixed voltage applications. The FSELx pins choose between division of the input reference frequency by one

or two. The frequency divider can be set individually for each output bank. The MPC9443 output banks are in high-impedance state by

deasserting the OEN pins. Asserting OEN will the enable output banks. Please see Table 4. Output High-Impedance Control (OE

details. The outputs can be synchronously stopped (logic low state). The outputs provide LVCMOS compatible levels with the capability

to drive terminated 50 Ω transmission lines. For series terminated transmission lines, each of the MPC9443 outputs can drive one or two

traces giving the devices an effective fanout of 1:32 at V
