9ZML1232E - 2:12 Low-Power PCIe Clock Mux
Pin-to-pin with improved performance

The 9ZML1232 is a 2-input/12-output differential mux for use in servers. It meets the demanding DB1200ZL performance specifications and utilizes Low-Power HCSL-compatible outputs to reduce power consumption and termination components. It is suitable for PCI-Express Gen1/2/3 or QPI/UPI applications, and uses a fixed external feedback to maintain low drift for demanding QPI/UPI applications.

Features

  • Fixed feedback path; 0ps input-to-output delay
  • 9 Selectable SMBus addresses; multiple devices can share same SMBus segment
  • Separate VDDIO for outputs; allows maximum power savings
  • PLL or bypass mode; PLL can dejitter incoming clock
  • Hardware or Software-selectable PLL BW; minimizes jitter peaking in downstream PLL's
  • Spread spectrum compatible; tracks spreading input clock for EMI reduction
  • SMBus Interface; unused outputs can be disabled
  • Differential outputs are Low/Low in power down; maximum power savings
