500DA-L Reclocking Distribution Amplifier for Digital Looping Frame
Revision 0.3 500DA-L - 1
1. OVERVIEW
The 500DA-L is a re-clocking distribution amplifier for use in the Evertz high density digital looping frame
(the 500FR-L-D). The 500DA-L supports all data rates included in SMPTE 259M (143 Mb/s - 360 Mb/s)
and SMPTE 344M (540 Mb/s), as well as DVB-ASI. The 500DA-L also features auto-equalized inputs with
eight serial outputs.
When inserted into the 500FR-L-D Frame (Digital with Loop Through), a passive loop
output is available to enable cascading of multiple DA cards. The passive loop is implemented on the
500FR-L-D back-plane. As a result, a failure of any single card or the removal of any single card does not
affect any other cards being used for signal distribution. Up to 16 500DA-L cards may be cascaded error
free in the 500FR-L-D frame.
The 500DA-L also features a re-clocker bypass to support operation with non-standard data rates, such as
SMPTE 310M and others.
Features
• Automatic equalization, rate detection and re-clocking for all SMPTE 259M (143 Mb/s - 360 Mb/s)
and SMPTE 344M (540 Mb/s) data rates
• Jumper selectable DVB-ASI mode of operation
• Jumper selectable non re-clocked mode for SMPTE 310M and other non-standard date rates
• Passive loop output when inserted into the 500FR-L-D
• Error free cascading of up to 16 modules within the 500FR-L-D
• Fully hot-swappable from front of frame with no BNC disconnect
• Independent isolated output drivers to ensure no cross channel loading effects (ie. 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
• VistaLINK®- capable for remote monitoring via SNMP (using VistaLINK®PRO) when installed in
500FR-L-D with 500FC VistaLINK®Frame Controller
