Not recommended for new designs.
Please use the GS12281 for new designs.
The GS12181 is a low-power, multi-rate, serial digital retiming cable driver supporting 12G UHD-SDI. It is designed to receive 100Ω differential input signals, automatically recover the embedded clock from the digital video signal and re-time the incoming data, and transmit the re-timed signal over 75Ω coaxial cables.

- SMPTE ST 2082-1, ST 2081-1, ST 424, ST 292-1 and ST 259 compliant output
- Support for DVB-ASI at 270Mb/s and MADI at 125Mb/s
- Low power operation: appro×. 340mW
- Single 1.8V power supply for analog and digital core, 2.5V or 3.3V for output supply
- Differential input support DC-coupling from 1.2V to 2.5V CML logic
- Automatic power down on loss of signal
- Programmable trace equalization to compensate for up to 20” FR4 at 11.88Gb/s
- 75Ω cable driver outputs
- High levels of pre-emphasis available (up to 8” of FR4) using higher output driver voltage supply
- Automatic/manual output slew rate control
- Individually selectable output pre-emphasis to compensate for FR4 losses after chip output at all rates
- Manual Bypass function for low data rates with slow rise/fall times
- Configurable automatic bypass for low data rates
- On-chip 100Ω differential input data termination and 75Ω output termination

Whether you are watching an action replay of a baseball game on a giant screen at a stadium, a movie on your large-screen TV or streaming a video on your laptop computer, a high-quality audiovisual (AV) experience is always expected. Ultra-High-Definition Serial Digital Interface (UHD-SDI) and High-Definition Multimedia Interface (HDMI) are two standards for digital AV transmission. UHD-SDI standardizes the transmission of uncompressed and unencrypted digital AV signals over coaxial or fiber optic cables. HDMI is a digital interface for transmitting high-definition, high-speed digital multi-track audio and uncompressed video signals from HDMI-compliant sources to AV displays. Even though they both can transport ultra-high-definition AV signals from a source to a display, HDMI is preferred to connect consumer gadgets such as computers, gaming consoles, Blu-ray/DVD players, televisions, projectors, etc. UHD-SDI is preferred for high-end applications such as professional indoor/outdoor video production and television broadcasts because it supports long-range transmission and a rugged connection with the help of a physical lock mechanism at each end of the cable. UHD-SDI coaxial cable can transfer signals up to 300 feet, whereas HDMI cables struggle with excessive signal degradation even within 50 feet. These two interfaces can be used together via an HDMI-SDI or SDI-HDMI converter. For example, as shown in figure 1, an HDMI display would be used for confidence monitoring of an SDI stream to avoid the need to use specially calibrated SDI-specific displays.

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.
