GS1672
Please use GS2972 for new designs.
The GS1672 is a complete SDI transmitter, generating a SMPTE 292M, SMPTE 259M-C or DVB-ASI compliant serial digital output signal.
The integrated ClockCleaner™ allows the device to accept parallel clocks with high input jitter, and still provide a SMPTE compliant serial digital output.
The device can operate in four basic user selectable modes: SMPTE mode, DVB-ASI mode, Data-Through mode, or Standby mode.
In SMPTE mode, the GS1672 performs all SMPTE processing features.
In DVB-ASI mode, the device will perform 8b/10b encoding prior to transmission.
In Data-Through mode, all SMPTE and DVB-ASI processing is disabled. The device can be used as a simple parallel to serial converter.
The device can also operate in a lower power Standby mode. In this mode, no signal is generated at the output.
The GS1672 includes a fully SMPTE-compliant cable driver for SMPTE 292M and SMPTE 259M-C interfaces. It features automatic dual slew-rate selection, depending on HD- or SD-SDI operational requirements.
In accordance with SMPTE 272M and SMPTE 299M, up to eight channels (two audio groups) of serial digital audio may be embedded into the video data stream. The input audio signal formats supported by the device include AES/EBU, I2S and serial audio. 16, 20 and 24-bit audio formats are supported at 48kHz synchronous for SD modes and 48kHz synchronous or asynchronous in HD modes.

READ NOWWhether 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.

READ NOWI 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.
