General Description

The Si53112 is a low-power, 12-output, differential clock buffer that meets all of the performance requirements of the Intel DB1200ZL specification.

The device is optimized for distributing reference clocks for Intel® QuickPath Interconnect (Intel QPI), PCIe Gen 1/Gen 2/Gen 3/Gen 4, SAS, SATA, and Intel Scalable Memory Interconnect (Intel SMI) applications.

The VCO of the device is optimized to support 100 MHz and 133 MHz operation.

Overview

Si53112 DB1200ZL 12-OUTPUT PCIE GEN 3 BUFFER.

Key Features

  • Twelve 0.7 V low-power, push-.
  • PLL or bypass mode pull, HCSL-compatible.
  • Spread spectrum tolerable PCIe Gen 3 outputs.
  • 1.05 to 3.3 V I/O supply voltage.
  • Individual OE HW pins for each output clock 100 MHz /133 MHz PLL operation, supports PCIe and QPI.
  • 50 ps output-to-output skew 50 ps cyc-cyc jitter (PLL mode) Low phase jitter (Intel QPI, PCIe Gen 1/2/3/4 common clock compliant).
  • PLL bandwidth SW SMBUS programming overrides the lat.
