9ZML1232数据手册集成电路（IC）的时钟发生器PLL频率合成器规格书PDF

描述 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 Gen1/2/3 or QPI/UPI applications, and uses a fixed external feedback to maintain low drift for demanding QPI/UPI applications.

特性 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
