The 9DML04 devices are 3.3V members of IDT's Full-Featured PCIe family. The 9DML04 supports PCIe Gen1–5 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.
 
For information regarding evaluation boards and material, please contact your local IDT sales representative.
 

Features

  • PCIe Gen1–5 CC compliant
  • PCIe Gen1–5 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 IDT application note AN-891.
  • Space saving 4 × 4mm 24-VFQFPN; minimal board space
