The GS9074A 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 GS9074A output when an approximate selected cable length is reached for SMPTE 259M signals. This feature allows the GS9074A to distinguish between low amplitude SD-SDI signals and noise at the input of the device. The serial digital outputs of the GS9074A may be forced to a mute state by applying a voltage to the MUTE pin. Power consumption is typically 215mW using a 3.3V power supply. The GS9074A is lead-free, and the encapsulation compound does not contain halogenated flame retardant (RoHS compliant).
