| Description |
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.
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.
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.
