GS12141 12G UHD-SDI Retiming Adaptive Cable Equalizer Four configurable GPIO pins for control or status Key Features monitoring 75 cable input interface with on-chip termination Wide operating temperature range: -40C to +85C SMPTE ST 2082-1, ST 2081-1, ST 424, ST 292-1 and ST Small 6mm x 4mm 40-pin QFN 259 compliant input/output Pb-free/Halogen-free/RoHS and WEEE compliant Multi-standard operation from 1Mb/s to 11.88Gb/s package In addition to standard SMPTE rates, the device also supports re-timing of DVB-ASI at 270Mb/s, and MADI Applications at 125Mb/s Next Generation 3D / 2D HFR HDTV and 2K D-Cinema, Automatic cable equalization. Typical equalized cable UHDTV1 and 4K D-Cinema end-equipment: Cameras, lengths of Belden 1694A cable: Monitors, Switchers, etc. 70m at 11.88Gb/s Next Generation 3G, 6G, and 12G UHD-SDI infrastructures 90m at 5.94Gb/s designed in support of UHDTV1, UHDTV2, 4K D-Cinema 180m at 2.97Gb/s and 3D HFR and HDR production image formats. 240m at 1.485Gb/s 400m at 270Mb/s Description Cable equalizer mode features: The GS12141 is a low-power, multi-rate re-timing Cable Programmable carrier detect with squelch Equalizer supporting rates up to 12G UHD-SDI. It is threshold adjustment designed to equalize and restore signals received over 70m Manual and automatic cable equalizer bypass coaxial cable at 12G, compensate for DC content of SMPTE pathological signals, and re-time the incoming data. The Trace driver features: device supports SMPTE ST 2082-1 (12G UHD-SDI), ST Integrated 100, differential output termination 2081-1 (6G UHD-SDI), ST 424 (3G SDI), ST 292-1 (HD-SDI), DC-coupling from 1.2V to 2.5V CML logic and ST 259 (SD-SDI) signals and is optimized for Trace driver data output pre-emphasis to performance at 11.88Gb/s. In addition to standard SMPTE compensate for up to 20 FR4 at 11.88Gb/s rates, the device also supports re-timing of DVB-ASI at 270Mb/s, and MADI at 125Mb/s. Manual or automatic re-timer bypass Manual or automatic Mute or disable on LOS The two trace drivers have highly configurable pre-emphasis and swing controls to compensate for long CDR features: trace and connector losses. Manual or automatic rate modes Since the GS12141 is a re-timing equalizer, extremely low Wide Loop bandwidth control output jitter is achievable even at extended cable lengths. Re-timing at the following data rates: 125Mb/s, Typical jitter performance versus cable length is as follows: 270Mb/s, 1.485Gb/s, 2.97Gb/s, 5.94Gb/s, 11.88Gb/s. This includes the f/1.001 rates. 70m at 11.88Gb/s: <0.2UI output jitter Single 1.8V power supply for analog and digital core 90m at 5.94Gb/s: <0.15UI output jitter 1.2V, 1.8V, or 2.5V for trace driver output supply 180m at 2.97Gb/s: <0.1UI output jitter GSPI serial control and monitoring interface 240m at 1.485Gb/s: <0.1UI output jitter 400m at 270Mb/s: <0.1UI output jitter GS12141 1 of 65 www.semtech.com Final Data Sheet Rev.8 Semtech PDS-060553 June 2018 Proprietary & ConfidentialCS SCLK SDIN SDOUT GPIO0 GPIO1 GPIO2 GPIO3 Control & Status Trace Driver Data: (Retime/ DDO0 Bypass) Pre-emphasis Cable SDI CDR Equalizer Data: Trace Driver (Retime/ Bypass) DDO1/RCO --------- Pre-emphasis Clock GS12141 Functional Block Diagram GS12141 2 of 65 www.semtech.com Final Data Sheet Rev.8 Semtech Proprietary & Confidential PDS-060553 June 2018
