9QXL2001C数据手册Renesas中文资料规格书

描述 Description

The 9QXL2001C is a 20-output very-low-additive phase jitter fanout buffer for PCIe Gen1 to Gen6 applications. The 9QXL2001C provides two methods to control output enables; standard OE# pins and SMBus enable bits, and a simple 3-wire serial interface (Side-Band Interface) that is independent of the SMBus. The Side-Band Interface is enabled via a hardware strap and operates simultaneously with the OE# pins and SMBus enable bits. It offers integrated terminations for 85Ω transmission lines.

特性 Features

• 8 OE# pins provide hardware control of 8 outputs
• 20 SMBus bits allow software control of each output
• 3-wire Side-Band Interface provides serial control of all 20 outputs at 25MHz rate
• 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
