AU5447
Features

• Low power HCSL (LP-HCSL) outputs with ZO = 85 Ω

• Flexible control via SMBus interface and hardware output-enable pins

• Low phase jitter: 40 fs – 50 fs typical, and 8 fs RMS after 

  PCIe Gen6 filter

• Additive phase jitter with DB2000Q filter ~ 10 fs RMS (typical)

• Output to Output Skew < 50 ps

• 3.3 V power supply and hardware-controlled low power mode

Applications

• Micro server and Tower server

• Rack server

• Storage area network and host bus adapter card

• Network attached storage

• Hardware accelerator

Advantages

• Fully compliant with Intel DB800Z specifications, suitable for 

  PCIe Gen1-6 or QP/UPI applications

• Equivalent with 85 Ω Terminations, saving power and board space, 

  no termination

• Spread spectrum compatible; tracks spreading input clock for 

  reducing EMI and improving system signal integrity 

• Compact QFN package and standard pin configuration accelerate 

  product development cycle
