Key Features

Multi-Rate Reclocking: Automatically detects, equalizes, and reclocks 3G-SDI (SMPTE ST 424, 3Gb/s), HD-SDI (ST 292-1, 1.5Gb/s), and SD-SDI (ST 259-1, 270Mbps).
1x7 Isolated Distribution: Provides seven independent outputs with isolated drivers to prevent cross-channel loading and support unterminated outputs.
Selectable Bypass Mode: Supports non-reclocked pass-through for SMPTE ST 344-1 (540Mbps), SD-SDI (360/143Mbps), SMPTE ST 310-1 (19.4Mbps), and DVB-ASI.
Long-Reach Cable Equalization: Supports coaxial runs up to 80m at 3Gb/s, 150m at 1.5Gb/s, and 350m at 270Mbps using Belden 1694A or equivalent.
Front Hot-Swappable Design: Enables module replacement from the front without disconnecting rear BNC cabling.
Input Loss Tally: Provides a Frame Status Bus tally output when the input signal is lost.
VistaLINK® Management: Supports remote monitoring and control through VistaLINK® and VUE control panels with a 7800FC Frame Controller.

Product Overview +

High-Density 3G/HD/SD-SDI Signal Distribution

The Evertz 7700DA7-3G is a high-performance 1x7 distribution amplifier designed for broadcast studios, live production trucks, and transmission headends requiring multi-rate serial digital video signal distribution. Reclocking incoming 3G-SDI, HD-SDI, and SD-SDI inputs, it delivers seven clean, jitter-suppressed outputs across a high-density 1-slot form factor.

Versatile Dual-Mode Operation & Long-Distance Equalization

Operating in dual processing modes, the card provides exceptional flexibility across legacy and modern broadcast standards:

Reclocking Mode: Reclocks 3 Gbps, 1.5 Gbps, and 270 Mbps signals with low wideband jitter (< 0.2 UI HD, < 0.3 UI 3G).
Non-Reclocking Mode: Remotely configurable pass-through for DVB-ASI, ATSC SMPTE ST 310-1 (19.4 Mbps), and secondary SDI bitrates.

The adaptive input circuit provides robust equalization to restore weak signals over long coaxial runs, achieving up to 80m at 3 Gbps, 150m at 1.5 Gbps, and 350m at 270 Mbps.

Maintenance & Modular VistaLINK® Integration

Engineered for maximum uptime, the 7700DA7-3G is fully hot-swappable from the front frame without disturbing rear BNC cabling. Diagnostic card-edge LEDs display signal rate detection, control mode status, and overall module health. When deployed in Evertz 7800FR (3RU), 7801FR (1RU), 350FR (3RU portable), or standalone enclosures paired with a 7800FC Frame Controller, it supports complete SNMP remote management and alarm reporting via VistaLINK®.
