GS6042
The GS6042 is a high-speed BiCMOS device designed to equalize and restore signals received over 75 Ohms coaxial cable.
The device is designed to support 6G UHD-SDI, SMPTE ST 424, SMPTE ST 292 and SMPTE ST 259, and is optimized for performance at 270Mb/s, 1.485Gb/s, 2.97Gb/s, and 5.94Gb/s.
Features
- Multi-standard operation from 125Mb/s to 5.94Gb/s
- SMPTE ST 2081, ST 424, ST 292, and ST 259-C compliant
- Automatic cable equalization
- Performance optimized for 270Mb/s, 1.485Gb/s, 2.97Gb/s, and 5.94Gb/s. Typical equalized length of Belden 1694A cable up to:
- 80m at 5.94Gb/s
- 210m at 2.97Gb/s
- 300m at 1.485Gb/s
- 550m at 270Mb/s
- Supports DVB-ASI at 270Mb/s
- Supports MADI at 125Mb/s
- Manual bypass (useful for low data rates with slow rise/fall times)
- Programmable carrier detect with squelch threshold adjustment
- Automatic power-down on loss of signal
- Standby power <35mW (typical)
- Differential output supports DC-coupling from +1.2V to +3.3V CML logic
- Option to compensate for 6dB flat attenuation prior to input of device
- Selectable output de-emphasis: 2dB, 4dB and 6dB
- Standard EIA/JEDEC logic control and status signal levels
- Single +3.3V power supply operation
- 180mW power consumption (typical)
- Wide operating temperature range of -40ºC to +85ºC
- Small footprint QFN package (4mm x 4mm)
- Footprint compatible with the GS2974A, GS2974B, GS2984, GS2994, and GS3440
- Pb-free and RoHS compliant
- SMPTE ST 2081, SMPTE ST 424, SMPTE ST 292, SMPTE ST 259 and AES10 coaxial cable serial digital interfaces

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.
