Features
- Fixed feedback path; 0ps input-to-output delay
- 9 selectable SMBus addresses; multiple devices can share the same SMBus segment
- Separate VDDIO for outputs; allows maximum power savings
- PLL or bypass mode; PLL can de-jitter incoming clock
- Hardware or software-selectable PLL BW; minimizes jitter peaking in downstream PLLs
- 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
Description
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 Gen 1/2/3 or QPI/UPI applications and uses fixed external feedback to maintain low drift for demanding QPI/UPI applications.
