VIA Pro266/PN266/CLE266/CM400 chipset for PIII/Tualatin/C3 Processor

The IDT950908 is part of a whole new line of IDT clock generators and buffers called TCH™ (Timing Control Hub). This part
incorporates IDT’s newest clock technology which offers more robust features and functionality. 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. M/N control can configure output frequency with resolution up to 0.1MHz increment.


  • 1 - Pair of differential CPU clocks @ 3.3V (CK408)/
  • 1 - Pair of differential open drain CPU clocks (K7)
  • 2 - Push pull CPUT_CS clocks @ 2.5V
  • 3 - AGP @ 3.3V
  • 7 - PCI @ 3.3V
  • 1 - 48MHz @ 3.3V fixed
  • 1 - 24_48MHz @ 3.3V
  • 2 - REF @ 3.3V, 14.318MHz
