DESCRIPTION

The ABB0302 is designed as a 2.5V buffer to

distribute high-speed clocks in PC applications.

The device has 24 outputs. These outputs can be

configured to support four unbuffered DDR

DIMMS. The ABB0302 can be used in

conjunction with a clock synthesizer for the VIA

Pro 266 chipset.

The ABB0302 also has an I2C interface, which

can enable or disable each output clock. When

powered up, all output clocks are enabled (have

internal pull ups).
