Overview

Description

The IDT9ZX21201 is a 12-output DB1200Z suitable for PCI Express® Gen3 or QPI applications. The part is backwards compatible to PCIe Gen1 and Gen2. A fixed external feedback maintains low drift for critical QPI applications. In bypass mode, the IDT9ZX21201 can provide outputs up to 150MHz.

Features

  • 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 < 0.2ps RMS
  • Space-saving 64-pin packages
  • Fixed feedback path/ 0ps input-to-output delay
  • 9 Selectable SMBus Addresses/Multiple devices can share the same SMBus Segment
  • 12 OE# pins/Hardware control of each output
  • PLL or bypass mode/PLL can dejitter incoming clock
  • 100MHz or 133MHz PLL mode operation/supports PCIe and QPI applications
  • Selectable PLL bandwidth/minimizes jitter peaking in downstream PLL's
  • Spread Spectrum Compatible/tracks spreading input clock for low EMI
  • Software control of PLL Bandwidth and Bypass Settings/ PLL can dejitter incoming clock (B Rev only)
