9QXL2001B中文资料20-Output DB2000QL PCIe Clock Buffer数据手册Renesas规格书

描述 Description

The 9QXL2001B is a 20-output very-low-additive phase jitter fanout buffer for PCIe Gen4, Gen5 and UPI applications. The 9QXL2001B provides two methods to control output enables; standard OE# pins and SMBus enable bits, or a simple 3-wire serial interface that is independent of the SMBus. The OE Control Mode is set via a hardware strap. It offers integrated terminations for 85Ω transmission lines.

特性 Features

• Traditional 8 OE# pins allow hardware control of 8 outputs and 20 SMBus bits allow software control of each output
• Simple 3-wire Side-Band Interface allows real-time control of all 20 outputs
• Outputs remain Low/Low when powered up with floating input clock
• Low-Power HCSL (LP-HCSL) outputs reduce device power consumption by 50%
• Zo = 85Ω outputs eliminate 80 resistors, saving 130mm2 of area
• 9 selectable SMBus addresses
• Spread spectrum compatible
• 6 × 6 mm dual-row 80-GQFN

应用 Application

• AI 加速卡电源定时系统
