9ZX21200 - 12-OUTPUT DIFFERENTIAL Z-BUFFER

General Description

The 9ZX21200 is a small-footprint 12-output differential buffer that meets all the performance requirements of the Intel DB1200Z specification.

The 9ZX21200 is backwards compatible to PCIe Gen1 and Gen2 applications.

A fixed, internal feedback path maintains low drift for critical QPI applications.

Key Features

  • Benefits.
  • Space-saving 56-pin package.
  • Fixed feedback path for 0ps input-to-output delay.
  • 9 Selectable SMBus Addresses; Mulitple devices can share the same SMBus Segment.
  • 4 OE# pins; Hardware control of four outputs.

12-OUTPUT DIFFERENTIAL Z-BUFFER FOR PCIE GEN3 AND QPI DATASHEET 9ZX21200 Description The 9ZX21200 is a small-footprint 12-output differential buffer that meets all the performance requirements of the Intel DB1200Z specification. The 9ZX21200 is backwards compatible to PCIe Gen1 and Gen2 applications. A fixed, internal feedback path maintains low drift for critical QPI applications. In bypass mode, the 9ZX21200 can provide outputs up to 150MHz. Recommended Application 12-output PCIe Gen3/ QPI differential buffer for Romley and newer platforms Key Specifications • Cycle-to-cycle jitter <50ps • Output-to-output skew < 65 ps • Input-to-output delay variation <50ps • PCIe Gen3 phase jitter < 1.0ps RMS • QPI 9.6GT/s 12UI phase jitter < 0.
