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).
