The EN334S/U device is a quad channel SDI receiver targeted for long reach performance using EX-SDI technology.

The EX-SDI is a visually lossless codec for Long Reach Solution, reducing transmission bandwidth carried on existing cables such as coax and UTP cables.

Especially the EX-SDI V2.0 technology allows transmission distance to achieve 500m or more on RG59 cables with 135Mbps SDI-based encoding. 

In addition , for increasing the distance, the EX-SDI TDM supports multiplexing (or de-multiplexing) multi-channel up to eight channels over a single of coax cable at 1.485Gbps bandwidth. 

For cost effectiveness, it highly integrates cable equalizers, de-serializers, audio de-embedders, and UCC-modulators, which dissipates low power consumption. It also features various outputs such as Frame-interleaving, Byte-interleaving and multiplexed format for H/W efficiency.
