Features
- Traditional 8 OE# pins allow hardware control of 8 outputs
- 20 SMBus bits enable software control of each output
- Simple 3-wire sideband interface enables real-time control of all 20 outputs
- Low-power HCSL (LP-HCSL) outputs reduce device power consumption by 50%
- 85Ω output impedance eliminates 80 resistors, saving 130mm² of board area
- 9 selectable SMBus addresses
- Spread-spectrum compatible
- Operating temperature range: -40°C to +105°C
- 6mm × 6mm VFQFPN package
Description
The 9QXL2002B is a 20-output very-low additive phase jitter fanout buffer for PCIe Gen1 to Gen7 applications. It provides three methods to control output enables: standard OE# pins, SMBus enable bits, and a simple 3-wire serial interface (side-band interface) that operates independently 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.
