特長
- PCIe Gen 1–4 CC compliant
- Supports PCIe Gen 2–3 SRIS compliant
- Supports PCIe SRnS compatible
- Direct connection to 100Ω transmission lines; saves 28 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 the application note AN-891.
- Space saving 5mm x 5mm 40-VFQFPN; minimal board space
説明
The 9DBL0741 7-output 3.3V PCIe fanout clock buffer is a member of Renesas' 3.3V full-featured PCIe clock family. The 9DBL0741 supports PCIe Gen 1-4 Common Clocked (CC) and PCIe Separate Reference Independent Spread (SRIS) systems. The device's integrated output terminations provide a direct connection to 100Ω transmission lines. The 9DBL07P1 can be factory programmed with a user-defined power-up default SMBus configuration.
