GS12241 12G UHD-SDI Re-timing Adaptive Cable Equalizer Key Features Additional Features 75 cable input interface with on-chip termination Single 1.8V power supply for analog and digital core SMPTE ST 2082-1, ST 2081-1, ST 424, ST 292-1 and ST 259 GSPI serial control and monitoring interface compliant input/output Four configurable GPIO pins for control or status monitoring Multi-standard operation from 1Mb/s to 11.88Gb/s Wide operating temperature range: -40C to +85C In addition to standard SMPTE rates, the device also supports Small 6mm x 4mm 40-pin QFN re-timing of DVB-ASI at 270Mb/s, and MADI at 125Mb/s Pin compatible with the GS12141, GS12142, and GS3241 3D Input Signal Eye Monitor Pb-free/Halogen-free/RoHS and WEEE compliant package PRBS generator and checker Automatic cable equalizationtypical equalized cable Applications lengths of Belden 1694A cable: Next Generation 12G UHD-SDI infrastructures designed to 80m at 11.88Gb/s support UHDTV1, UHDTV2, 4K D-Cinema and 3D HFR and HDR 100m at 5.94Gb/s production image formats. Typical applications: Monitors, 190m at 2.97Gb/s Switchers, Distribution Amplifiers and Routers. 260m at 1.485Gb/s 450m at 270Mb/s and 125Mb/s Description Cable equalizer mode features: The GS12241 is a low-power, multi-rate re-timing Cable Equalizer Automatic power down on loss of signal supporting rates up to 12G UHD-SDI. It is designed to equalize and Programmable carrier detect with squelch threshold restore signals received over 80m coaxial cable at 12G, adjustment compensate for DC content of SMPTE pathological signals, and Programmable launch swing compensation for re-time the incoming data. non-compliant source The integrated eye monitor provides non-disruptive mission Manual and automatic cable equalizer bypass mode analysis of the post equalized input signal. The 256x128 Trace driver features: resolution scan matrix allows accurate signal analysis to speed up Integrated 100, differential output termination prototyping and enable field analysis. Extends output DC-coupling support with 1.2V to 2.5V Built in macros enable customizable cross section analysis and output supply range quick horizontal and vertical eye opening measurements. Trace driver data output pre-emphasis to compensate for With high phase consistency between scans and configurable up to 20 FR4 at 11.88Gb/s space and time thresholds, algorithms can be deployed in the field to analyse long term signal quality variation (Bathtub Plot) to Manual or automatic re-timer bypass reduce costly system installation debug time for intermittent Manual or automatic mute or disable on LOS errors. CDR features: The two independently controlled trace drivers feature highly Manual or automatic rate modes configurable pre-emphasis and swing controls to compensate for Wide Loop bandwidth control long trace and connector losses. The pre-emphasis pulse width Re-timing at the following data rates: 125Mb/s, 270Mb/s, can be optimized to compensate for perturbations to frequency 1.485Gb/s, 2.97Gb/s, 5.94Gb/s, and 11.88Gb/sthis response of transmission lines due to vias connectors and stubs. includes the f/1.001 rates The GS12241 is pin compatible with the GS12141 single input and the GS12142 dual input 12G UHD-SDI Multi-rate Re-timing Cable Equalizers, as well as the GS3241 3G SDI Multi-rate Re-timing Cable Equalizer. Note: For the GS12241 to be pin compatible with the GS12142, careful design considerations are required. Contact for your local Semtech FAE for details.
