DESCRIPTIONS

The PLL103-06 is designed as a 3.3V/2.5V buffer to distribute high-speed clocks in PC applications. The device has 12 outputs. These outputs can be configured to support 3 unbuffered standard SDR (Single Data Rate) DIMMS and 2 DDR DIMMS. The PLL103-06 can be used in conjunction with the PLL202-04 or similar clock synthesizer for the VIA Pro 266 chipset.
