General Description

: IDTCV149 is a 56 pin clock device for AMD advance K8 processors.

The CPU output buffer is designed to support up to 400MHz processor.

This device also implements Band-gap referenced IREF to reduce the impact of VDD variation on differential outputs, which can provide more robust system performance.

Key Features

  • One high precision N and SSC programmable PLL for CPU.
  • One high precision N and SSC programmable PLL for SRC[2:1].
  • One high precision N and SSC programmable PLL for SRC0 [7:3] (PCI Express).
  • One high precision PLL for 48MHz.
  • Band-gap circuit for differential outputs.
  • Support multiple spread spectrum modulation, down and center.
  • Support SMBus block read/write, index read/write.
  • Selectable output strength for REF, PCI, 48MHz.
