GS6042 6G UHD-SDI/3G/HD/SD Adaptive Cable Equalizer Gennum Products Key Features Description Supports data rates from 125Mb/s to 6.25Gb/s The GS6042 is a high-speed BiCMOS device designed to optimally equalize and restore signals received over 75 SMPTE ST 2081 (proposed), SMPTE ST 424, coaxial cable. SMPTE ST 292, and SMPTE ST 259 compliant The device supports data rates up to 6.25Gb/s while being Automatic cable equalization optimized for the proposed SMPTE ST 2081, as well as Typical equalized length of Belden 1694A cable: SMPTE ST 424, SMPTE ST 292, and SMPTE ST 259. 80m at 5.94Gb/s The GS6042 features DC restoration to compensate for the 210m at 2.97Gb/s DC content of SMPTE pathological signals. 300m at 1.485Gb/s The Carrier Detect output pin (CD) indicates whether an input signal has been detected. It can be connected 500m at 270Mb/s directly to the SLEEP pin to enable automatic sleep on loss Supports DVB-ASI at 270Mb/s of input. Supports MADI at 125Mb/s A CD threshold is set via the SQ ADJ pin, allowing the Manual bypass control GS6042 to distinguish between small amplitude SDI signals and noise at the input of the device. Programmable carrier detect with squelch threshold adjustment The equalizing and DC restore stages are disengaged and no equalization occurs when the BYPASS pin is HIGH. This is Automatic power-down on loss of signal useful for signals launched at the signal source with low Differential output supports DC-coupling from +1.2V data rates and/or slow rise/fall times. to +3.3V CML logic The GS6042 features a gain selection pin (GAIN SEL) which Optional 6dB flat band gain on input can be used to compensate for 6dB flat attenuation prior to Selectable output de-emphasis: 2dB, 6dB, and 8dB the input of the device. Standard EIA/JEDEC logic for control/status signals The differential output can be DC-coupled to Semtechs Single +3.3V power supply operation reclockers and cable drivers, as well as industry-standard CML logic by changing the voltage applied to the 180mW power consumption (35mW in sleep) VCC O pin. In general, DC-coupling to any termination Operating temperature range: -40C to +85C voltage between +1.2V and +3.3V is supported. Small footprint QFN package (4mm x 4mm) The GS6042 also features programmable output Footprint compatible with the GS2974A, GS2974B, de-emphasis with three user-selectable operating levels to GS2984, GS2994, and GS3440 support long PCB traces at the output of the device. Pb-free and RoHS compliant Power consumption of the GS6042 is typically 180mW when its output is DC-coupled at +1.2V. Applications The GS6042 is Pb-free, and the encapsulation compound SMPTE ST 2081 (proposed), SMPTE ST 424, does not contain halogenated flame retardant. This SMPTE ST 292, and SMPTE ST 259 coaxial cable serial component and all homogeneous subcomponents are digital interfaces RoHS compliant.
