The GX3290 is a low-power, high-speed 290 x 290 crosspoint switch, with robust signal conditioning circuits for driving and receiving high-speed signals through backplanes.
The device consumes as low as 34W of power (typical) with all channels operational, and features sophisticated, dynamically scalable power management. Unused portions of the core are automatically turned off without affecting the operation of the remaining channels.
The signal conditioning features of the GX3290 include per-input programmable equalization and per-output programmable de-emphasis. The input equalizer removes ISI jitter—typically caused by PCB trace losses—by opening the input data eye in applications where long PCB traces and connectors are used. There are four settings available for the input equalizer, allowing flexibility in adjusting the equalization level on a per-input basis.
Output de-emphasis capability provides a boost of the high-frequency content of the output signal, such that the data eye remains open after passing through a long interconnect of PCB traces and connectors. There are four de-emphasis settings that can be enabled on a per-output basis.
System test features, such as a programmable PRBS pattern generator and checker, can be applied to any input or output of the device as appropriate.
The pattern generators can be individually applied to any output of the device without impacting the normal operation of any other channel. Broadcast and multicast features are also available.
The chip features eight independent strobe lines, UPDATE_EN[7:0], which are used to determine the timing of the output updates. Any output can be linked to any strobe.

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.
