SI53112 Datasheet Db1200zl 12-output Pcie Gen 3 Buffer

Manufacturer: Silicon Laboratories

Overview: Si53112 DB1200ZL 12-OUTPUT PCIE GEN 3 BUFFER.

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.

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.
