Gennum announced today a two chip transmitter/receive chip-set for delivering high definition (HD) video over coaxial cable lengths up to and beyond 100 metres. The chip-set, called Aviia GV7601 (receiver) and GV7600 (transmitter), allows users to upgrade existing analogue video over coax applications to full HD video.
Both the GV7600 and GV7601 are being designed into first generation High 
Definition closed circuit television (HDcctv 1.0) cameras and DVRs today, allowing closed circuit television system customers that currently use coaxial cable to support HD.
By using Gennum's HD Transmitter/Receiver solution customers can avoid the expense and disruption of a full system infrastructure upgrade while gaining all the benefits of full bandwidth HD over existing coax cables.
"Aviia (Advanced Video Interface for Industrial Applications) 
brings the image quality benefits of HD to a variety of industrial applications like security and surveillance where leveraging installed cabling infrastructure enables economical and quick upgrades," said Vijay Sharma, director of product marketing, Gennum
Aviia is a real-time A/V interface ideal for low latency, frame rate critical applications where high image quality and reliability are required, and provides bi-directional communications and Power-over-Coax, allowing both control and powering of remote devices, such as cameras.
The bi-directional communications channel can be used to send Pan Tilt Zoom (PTZ) configuration and status data. The Aviia interface can also be configured to provide bi-directional audio for intercom applications.
The GV7601 is an Aviia HD Receiver with integrated cable equalization technology. When used in conjunction with the GV7600 Aviia HD Transmitter, it provides a complete two-chip long reach (150 metres) A/V interface over a single coax.
The GV7601 supports both Standard Definition (SD) & High Definition (HD) video formats up to 1080p at 50/60 Hz (Full HD) and features an integrated audio de-embedder supporting extraction of up to 8 channels of digital audio.
Long reach HD cable performance includes up to 230m using high quality 75-ohm coaxial cable (Belden 1694A or equivalent) and up to 160m typical using RG59 or equivalent (commonly used in analogue video CCTV installations).
The GV7601 offers low power operation, typically 570mW at HD and comes in a small 100-BGA package (11mm x 11mm). The GV7601 is ideal for a wide range of industrial A/V markets and applications, including: Video Surveillance, Videoconferencing, Machine Vision, Digital Signage & Large Venue Displays, Industrial A/V and Medical Imaging.
The GV7601 and GV7600 are in full production with a reference design kit for both parts available now.
