SI52112-B3 - PCI-EXPRESS GEN 2 DUAL OUTPUT CLOCK GENERATOR

General Description

Si52112-B3/B4 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 and Gen 2 specifications.

Key Features

  • PCI-Express Gen 1 and Gen 2.
  • Extended Temperature: compliant.
  • 40 to 85 °C.
  • Low power HCSL differential.
  • 3.3 V Power supply output buffers.
  • Small package 10-pin TDFN.
  • Supports Serial-ATA (SATA) at (3x3 mm) 100 MHz.
  • Si52112-B3 does not support.
  • No termination resistors required spread spectrum outputs.
  • 25 MHz Crystal Input or Clock.
  • Si52112-B4 supports 0.5% down input spread outputs.
  • Triangular spread spectrum profile f.
