Clock for Others

Part No. W83195BG-505
Datasheet N/A
Description W83195BG-505 is a Clock Synthesizer meets AMD ATHLON 64 and OPTERON Processors series chipset, which provides all clocks required for high-speed microprocessor and step-less frequency programming and 32 different frequencies of CPU, AGP, PCI, PCI-Express clocks setting. All clocks are externally selectable with smooth transitions. Employing the use of a serially programmable I2C interface, this device can adjust the output clocks by configuring the frequency setting, the output divider ratios, selecting the ideal spread percentage, the output skew, the output strength, and enabling/disabling each individual output clock. By the way, the W83195BG-505 also has watchdog timer and reset out pin to support auto-reset when systems hanging caused by improper frequency setting.
Features
  • 2 pair 3.3V push-pull differential clock outputs for CPU and Chipset
  • 6 PCI-Ex differential pairs, 3x AGP clock output, and 6x PCI synchronous clocks
  • 1x 48MHz clock outputs, 1x 24_48MHz for I/O chip, and 2x REF 14.318MHz clock outputs
  • I2C 2-Wire serial interface supports block and byte mode read/write
  • Step-less frequency programming
  • Smooth frequency switch with selections from 100 to 400MHz
  • Programmable clock outputs Slew rate control and Skew control
  • +/- 0.5% center type spread spectrum in table mode or programmable S.S.T. scale to reduce EMI
  • Programmable registers to enable/stop each output and select modes
  • Watch dog timer and RESET# output pins
