DESCRIPTION

The PLL103-02 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 PLL103-02 can be used in conjunction with a

clock synthesizer for the VIA Pro 266 chipset.

The PLL103-02 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).
