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

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 de-jitter incoming clock
  • Selectable PLL bandwidth minimizes jitter peaking in downstream PLLs
  • Spread spectrum compatible
  • -40 °C to +85 °C device available; supports demanding environmental applications

Description
