Features
- PCIe Gen 1–7 CC compliant
- PCIe Gen 1–7 SRIS compliant
- Supports PCIe SRnS clocking
- Direct connection to 100Ω (xx42) or 85Ω (xx52) transmission lines; saves 16 resistors compared to standard PCIe devices
- Spread spectrum tolerant; allows reduction of EMI
- Selectable asynchronous or glitch-free switching; allows the mux to be selected at power up even if both inputs are not running, then transition to glitch-free switching mode
- Easy AC coupling to other logic families, see application note AN-891.
- Space saving 4mm × 4mm 24-VFQFPN; minimal board space
Description
The 9DML04 devices are 3.3V members of Renesas' full-featured PCIe family. The 9DML04 supports PCIe Gen 1–7 Common Clocked (CC), Separate Reference no Spread (SRnS), and Separate Reference Independent Spread (SRIS) architectures. The part provides a choice of asynchronous and glitch-free switching modes and offers a choice of integrated output terminations providing direct connection to 85Ω or 100Ω transmission lines. The 9DML04P1 can be factory programmed with a user-defined power-up default SMBus configuration.
