GV8601
The GV8601 is a high-speed BiCMOS integrated circuit designed to equalize and restore signals received over 75 ohms coaxial cable. The GV8601 is designed to support HDcctv 1.0, ST 292 and ST 424, and is optimized for performance at 1.485Gb/s and 2.97Gb/s serial data. The GV8601 features DC restoration to compensate for the DC content of HDcctv 1.1 pathological test patterns.

I designed my first product using the Serial Digital Interface (SDI) back in 1996, and little did I know that this fledgling coax-based video interface standard would dominate my career for the next 20+ years. Back then, SDI was limited to carrying Standard Definition (SD) digital video at 270 Megabits per second (Mbps), but would evolve to higher and higher data rates to carry High Definition 720p, 1080i and 1080p, and most recently 4K Ultra High Definition (UHD) video, at cable lengths that were not thought possible. The convenience of a low cost single conductor coaxial copper cable, capable of carrying 4K video up to 100m has meant that SDI has become the de facto AV connectivity of choice in markets such as broadcast, Pro AV, medical and surveillance.
