特性
- Loss of Signal (LOS) output; supports fault tolerant systems
- Supports PCIe Gen 1–5 CC and IR in fanout mode
- Supports PCIe Gen 1–5 CC in High Bandwidth Zero Delay Buffer (ZDB) mode
- Direct connection to 100Ω transmission lines; saves 24 resistors compared to standard PCIe devices
- Spread spectrum tolerant; allows reduction of EMI
- Pin/SMBus selectable PLL bandwidth and PLL Bypass; minimize phase jitter for each application
- Easy AC coupling to other logic families, see application note AN-891.
- Space saving 5mm × 5mm 40-VFQFPN; minimal board space
