Clock for Others

Part No.	W83195CG-382 W83195WG-382
Datasheet	N/A
Description	W83195WG-382/W83195CG-382 is a Clock Synthesizer for ATI K8 serial chipsets, which provides all clocks required for the high-speed microprocessor and step-less frequency programming and 32 different frequencies of CPU, PCI, and SRC clocks setting, all clocks are externally selectable with smooth transitions. W83195WG-382/ W83195CG-382 has watchdog timer and reset output pin to support auto-reset when systems hanging caused by improper frequency setting. It also support CPU TURBO function when system has heavy loading. W83195WG-382/W83195CG-382 provides I²C serial bus interface to program the registers to enable or disable each clock outputs and provides programmable S.S.T. scale to reduce EMI. It accepts a 14.318 MHz reference crystal as its input and runs on a 3.3V supply.
Features	2 pair push-pull Differential clock outputs for CPU. 6 pair current-mode Differential clock outputs for SRC. 2 pair current-mode Differential clock outputs for ATIG programmable. 1x PCI clock output, and 1x 48 MHz clock output for USB. 3x 14.318MHz REF clock outputs, and 1x HTT 66MHz clock output. Smooth frequency switch with selections from 100 to 400MHz. Step-less frequency programming. I²C 2-wire serial interface and support byte read/write and block read/write. Programmable S.S.T. scale to reduce EMI in M/N mode. Programmable registers to enable/disable each output and select modes. Programmable clock outputs slew rate control and skew control. Watch Dog Timer and RESET# output pins, and CPU TURBO function support.
