DTA-2142 Features

  • Universal parallel port for Rx and Tx of 8-bit data with valid and sync signals at clock rates up to 108MHz
  • Serial port is software-selectable input or output, DVB-ASI or SDI
  • The parallel port supports several modes, including DVB-SPI with boosted clock range, transport stream with fixed clock and valid, serial with explicit clock and BT-656 for uncompressed SD video
  • External clock input that can be used as master clock for serial and/or parallel port
  • BNC connector on PCI bracket can be used as serial port (default) or as external clock input by reconnecting coax cable to the external clock input MCX connector
  • I/O standard is selectable M-LVDS or LVTTL
  • Short-circuit detection on parallel port
  • Each port has on-board 32-Mbytes buffer

DTA-2142 Applications

  • General purpose lab card for generating and capturing of (un)compressed digital video and other 8-bit or 10-bit signals
  • Universal stream station
