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 85Ω transmission lines; saves 8 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 4mm × 4mm 24-VFQFPN; minimal board space
描述
The 9DBL0253 zero-delay/fanout buffer is a low-power high-performance member of Renesas' full-featured PCIe family. The buffer supports PCIe Gen 1–5 and provides a Loss of Signal (LOS) indicator. The device is an easy upgrade from the 9DBL0252.
