NOTICE - The following device(s) are recommended alternatives:
9ZXL1231E - DB1200ZL 12-Output Low Power HCSL Buffer
Pin-to-pin with improved performance

The 9ZXL1231 meets the demanding requirements of the Intel DB1200ZL specification, including the critical low-drift requirements of Intel CPUs.

Features

  • Low-power push-pull HCSL outputs; eliminate 24 resistors, save 41mm² of area
  • Pin-compatible to 9ZX21201 provides easy path to >50% power savings
  • Space-saving 64-pin VFQFPN package
  • Fixed feedback path for 0ps input-to-output delay
  • 9 Selectable SMBus Addresses
  • 12 OE# pins provide hardware control of each output
  • PLL or bypass mode; PLL can dejitter incoming clock
  • Selectable PLL bandwidth minimizes jitter peaking in downstream PLL's
  • Spread Spectrum Compatible
  • -40°C to +85°C device available; supports demanding environmental applications
