The GS2988 is a SMPTE-compatible, dual-output cable driver which supports data rates from 270Mb/s to 2.97Gb/s. The GS2988 is a high-speed BiCMOS integrated circuit designed to drive one or two 75Ω coaxial cables.
The GS2988 may drive data rates up to 2.97Gbps and provides two selectable slew rates in order to achieve compliance to SMPTE 424M, SMPTE 292M and SMPTE 259M. The GS2988 accepts industry-standard differential input levels including LVPECL and CML.
Input trace equalization compensates for up to 10 inches of FR4 trace loss. This feature can be disabled using the EQ_EN pin. The DISABLE pin powers-down the output driver, leaving the serial data output in a high-impedance state. The GS2988 features adjustable output swing using an external bias resistor. The single-ended output swing is adjustable from 500mVpp to 1800mVpp. An output signal presence function, the OSP pin, indicates whether an active signal is present at the output of the GS2988.
The GS2988 can be powered from either a 3.3V or a 2.5V supply. Power consumption is typically 125mW using a 2.5V power supply.
The GS2988 is Pb-free, and the encapsulation compound does not contain halogenated flame retardant. This component and all homogeneous subcomponents are RoHS compliant.
The GS2988 is drop-in compatible with Semtech's GS6080 6G UHD-SDI cable driver.

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.
