特性
- 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 a 25MHz rate
- Outputs remain Low/Low when powered up with a 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
- 6mm × 6mm dual-row 80-GQFN
9QXL2001C - Block Diagram
描述
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.
