Key Features

Dual Digital & Analog Distribution: Supports SMPTE ST 259-C 270Mb/s SD-SDI input with jumper-selectable reclocked SD-SDI or NTSC/PAL composite outputs.
Flexible Distribution Modes: Available as a 1x7 single-channel DA (7700VMDA) or dual-channel 1x3/single-channel 1x6 DA (7700VMDA-2Q).
Long-Reach Equalization: Automatically compensates for cable losses up to 300m over Belden 8281 coaxial cable at 270Mb/s.
Isolated Output Drivers: Provides independent outputs to prevent cross-channel loading without requiring termination on unused BNC outputs.
Embedded Audio Preservation: Transparently passes SMPTE ST 272-A embedded audio to all reclocked SD-SDI outputs.
VistaLINK® Centralized Monitoring: Provides real-time signal health monitoring and telemetry via SNMP with an Evertz 7800FC Frame Controller.

Product Overview +

High-Density SD-SDI Reclocking & Analog Conversion

The Evertz 7700VMDA series offers a reliable, cost-effective solution for facility signal distribution and local video monitoring. By taking standard-definition SMPTE ST 259 serial digital video, each module can distribute reclocked digital streams alongside composite analog encodings for feeding Legacy equipment, analog picture monitors, or master control routing panels.

Versatile Channel Routing & Isolated Signal Drivers

Configurable Output Modes: The standard 7700VMDA supports up to seven outputs individually configured for digital SDI or composite video via jumper selection. The 7700VMDA-2Q offers two independent video channels, each supporting three selectable outputs or combining into a single 1x6 DA.
No-Load Isolated Outputs: Each BNC output driver is fully isolated from adjacent channels. Unused coaxial ports do not require 75Ω termination and won't cause impedance mismatch or loading degradation on active outputs.
Signal Reclocking & Recovery: Reclaims signal integrity across long coaxial runs with automatic equalization up to 300m and ultra-low jitter reclocking (< 0.2 UI).

Modular Frame Integration & SNMP Telemetry

Designed for single-slot deployment, 7700VMDA modules fit seamlessly into Evertz 3RU 7800FR (15 slots), 1RU 7801FR (4 slots), 3RU 350FR portable chassis (7 slots), or standalone desktop enclosures. Card-edge LEDs give instant visual diagnostics for signal presence and module status, while full SNMP control is accessible via VistaLINK® NMS.
