MPC9140 - 1:18 LVCMOS FANOUT BUFFER

General Description

Pin Name BUF_IN SDRAM0:17 SDATA SCLK OE VDD VSS I/O I O I/O I I

3.3V CMOS clock input 3.3V CMOS SDRAM clock outputs Serial data for configuration control Serial clock input for configuration control.

Key Features

  • 18 low skew outputs optimized to drive the clock inputs of standard unbuffered SDRAM modules. Standard unbuffered SDRAM modules require four clocks per module allowing for the device to drive up to four modules. The output buffers have been optimized to drive the load presented by the SDRAM module. The MPC9140 provides output shut off capabilities via an I2C serial port for.

MOTOROLA SEMICONDUCTOR TECHNICAL DATA Product Preview 1:18 LVCMOS Fanout Buffer The MPC9140 is a 1:18 LVCMOS fanout buffer targeted to support Intel based Pentium II™ microprocessor chip sets. The device features 18 low skew outputs optimized to drive the clock inputs of standard unbuffered SDRAM modules. Standard unbuffered SDRAM modules require four clocks per module allowing for the device to drive up to four modules. The output buffers have been optimized to drive the load presented by the SDRAM module. The MPC9140 provides output shut off capabilities via an I2C serial port for applications which plan to use fewer than four modules and desire to minimize the power dissipation of the chip.
