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

Advance

 

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 adapter design complies with the XMC specification (ANSI/VITA 42.3-2006) and the Conduction-Cooled XMC (CCXMC) specification (ANSI/VITA 20-2005 (S2018)) and is available in a ruggedised conduction-cooled version with backplane I/O.

Architecture

The 8-Channel High-Speed Serial I/O XMC Adapter uses a single Xilinx Spartan-6 or Artix -7 Field-Programmable Gate Array (FPGA) as Serial Communications Controller. The Artix -7 FPGA can easily be configured to implement different serial protocols, thus allowing the adapters to keep up with technological advances. The Xilinx HSDLC IP core implements a controller for the High-Level Data Link Control (HDLC) and the Synchronous Data Link Control (SDLC) protocols. It is based on the Intel 8XC152 Global Serial Channel (GSC) operating in SDLC mode and adds features to support HDLC or proprietary frame transmission under host processor control. The HSDLC IP core operates as a peripheral to the serial I/O controller. Control and status registers are accessible via an Advanced Peripheral Bus (APB) and a comprehensive set of interrupt signals facilitates interrupt-based operation.

Features

  • Cost-effective and flexible option for systems that require both high-speed, real-time communication links as well as some low-speed serial links
  • Offers independent I/O processing offboard the host
  • up to four independent oscillators
  • eight indicators LEDs

Applications

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