NOTICE - The following device(s) are recommended alternatives:

The 9ZXL1230 is a small-footprint, low power 12-output differential buffer that meets all the performance requirements of the Intel DB1200ZL specification. It is pin-compatible to the 9ZX21200, while consuming over 50% less power. The 9ZXL1230 is backwards compatible to PCIe Gen1, Gen2 and QPI 6.4GT/s specifications. A fixed, internal feedback path maintains low drift for critical QPI applications.

Features

  • 12 - 0.7V low-power HCSL output pairs
  • Save power and board space - no Rp
  • Pin-compatible to 9ZX21200 provides easy path to >50% power savings
  • Space-saving 56-pin QFN package
  • Fixed feedback path for 0ps input-to-output delay
  • 9 Selectable SMBus Addresses
  • 4 OE# pins allow smaller form factor
  • PLL or bypass mode
  • PLL can dejitter incoming clock
  • 100MHz or 133MHz PLL mode operation for PCIe and QPI applications
  • Selectable PLL bandwidth minimizes jitter peaking in downstream PLL's
  • Spread Spectrum Compatible
