The Evertz 500DA Reclocking Distribution Amplifier provides inexpensive distribution of your SMPTE ST 310 and SMPTE ST 259 serial digital video signal at rates of 19.4Mb/s and 143Mb/s to 540Mb/s. Ideal in applications where a large quantity of outputs are required, the DA features an auto-equalized input with nine isolated reclocked outputs. The input also features an isolated return that is capacitively coupled to ground.

The 500DA has been designed for use as a SMPTE ST 310 (19.4Mb/s), DVB-ASI or SMPTE ST 259 distribution product. SMPTE ST 310 support is selected by setting a rate select jumper.

The 500DA is housed in the 3RU 500FR Exponent frame that will hold up to 16 modules.


  • Normal mode for SMPTE ST 259 (143 to 540Mb/s) or DVB/ASI signals - auto detects correct bitrate
  • Jumper selectable mode for SMPTE ST 310 (19.4Mb/s)
  • Fully hot-swappable from front of frame with no BNC disconnect required
  • Independent isolated output drivers to ensure no cross channel loading effects (i.e. no need to terminate unused outputs)
  • Outputs maintain polarity from input to output for DVB-ASI applications
  • Tally output on Frame Status bus upon loss of input signal for quality monitoring
  • VistaLINK® capable for remote monitoring via SNMP (using VistaLINK® PRO) when installed in 500FR frame with 500FC VistaLINK® Frame Controller
  • Input
  • SMPTE ST 259 A, B, C, D (143Mb/s to 540Mb/s), DVB-ASI, SMPTE ST 310 (19.4Mb/s) (jumper selectable)
  • Return Loss > 15dB up to 540Mb/s
  • 440m auto eq. at 270Mb/s (Belden 1694A)
  • 380m auto eq. at 270Mb/s (Belden 1694A) with HD SDI modules within 500FR
