DESCRIPTIONS

The PLL103-02 Rev.D 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 Rev.D can be used in conjunction with the PLL202-04 or similar clock synthesizer for the VIA Pro 266 chipset. The PLL103-02 Rev.D also has an I2C interface, which can enable or disable each output clock. When power up, all output clocks are enabled (has internal pull up).
