The ANA is the analog chip used on the Xenon motherboard. It contains the video encoders, DACs, clock generators (unused), thermal sensor circuits, fan driver op-amps, and some of the Power On Reset logic.

The chip was developed by Microsoft.

Specifications

  • Digital video encoder with 4 DACs
  • 5 thermal diode channels
  • 2 fan driver op-amps
  • Power on reset logic cell
  • Clock synthesizer:
    • 4x 100MHz differential: CPU, GPU, PCIe, SATA
    • 1x 48MHz single ended: SMC, USB
    • 2x 25MHz single ended: Ethernet, SATA
    • 1x 24.576MHz single ended: Audio
    • 2x programmable clocks: DVE video, Pixel
  • A00 stepping
  • 180nm process
  • 1.3W TDP

Details

The clock generators on the ANA are not used due to excessive PLL jitter. The Backup Clock Generator is used instead to generate system clocks. ANA still generates the video and audio clocks. The PLL jitter issue was fixed in HANA.
