The 9QXL2001 is a 20-output very-low-additive phase jitter fanout buffer for PCIe Gen4, Gen5 and UPI applications. The 9QXL2001 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.
特長
- 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
