SI52112-A2 - PCI-EXPRESS GEN 1 DUAL OUTPUT CLOCK GENERATOR

Download the SI52112-A2 datasheet PDF. This datasheet also covers the SI52112-A1 variant, as both devices belong to the same pci-express gen 1 dual output clock generator family and are provided as variant models within a single manufacturer datasheet.

General Description

Si52112-A1/A2 is a high-performance, PCIe clock generator that can source two PCIe clocks from a 25 MHz crystal or clock input.

The clock outputs are compliant to PCIe Gen 1 specifications.

Key Features

  • PCI-Express Gen 1 compliant.
  • 3.3 V Power supply.
  • Low power HCSL differential output buffers.
  • Small package 10-pin TDFN (3x3 mm).
  • Supports Serial-ATA (SATA) at.
  • Si52112-A1 does not support 100 MHz spread spectrum outputs.
  • No termination resistors required.
  • Si52112-A2 supports 0.5% down.
  • 25 MHz Crystal Input or Clock spread outputs input.
  • For PCIe Gen 2.
