The GS1574 is designed to support SMPTE 292M, SMPTE 344M and SMPTE 259M, and is optimized for performance at 270Mb/s and 1.485Gb/s. The GS1574 features DC restoration to compensate for the DC content of SMPTE pathological test patterns. A voltage programmable mute threshold (MCLADJ) is included to allow muting of the GS1574 output when an approximate selected cable length is reached for SMPTE 259M signals. This feature allows the GS1574 to distinguish between low amplitude SD-SDI signals and noise at the input of the device. The serial digital outputs of the GS1574 may be forced to a mute state by applying a voltage to the MUTE pin. Power consumption is typically 270mW using a 3.3V power supply. The GS1574 is lead-free, and the encapsulation compound does not contain halogenated flame retardant.
