8-Channel Ultra High-Speed Serial I/O PMC Adapter : New Generation



PDF print version of this specification

The 8-Channel Ultra High-Speed Serial I/O PMC Adapter provides eight channels of simultaneous, high-speed (>20 Mbit/s), bi-directional serial communications. All channels are jumper configurable as RS232/422/485. This adapter also supports a number of UART (Universal Asynchronous Receiver/Transmitter) (<1 Mbit/s) channels.

The board design complies with the 3U cPCI specification (PICMG 2.0 (R 3.0)) and is available in commercial, industrial, and ruggedised grades and in air-cooled and conduction-cooled versions with front panel or backplane I/O.

The 8-Channel Ultra High-Speed Serial I/O PMC Adapter is an intelligent I/O board designed with an NXP PowerQUICC II Integrated PowerPC Microprocessor as communication controller. The PowerQUICC II processor can easily be configured to implement different serial protocols, thus allowing the board to keep up with technological advances. All high-speed serial I/O channels are implemented using the PowerQUICC II.


  • cost-effective and flexible option for systems that require both a large number of high-speed, real-time communication links, as well as some low-speed serial links
  • offers independent I/O processing offboard the host


  • Distributed real-time applications in harsh environments
  • Mission-critical applications
  • Avionics
  • Vetronics
  • High-speed sensor integration
  • Legacy connectivity
