Semtech GS2972 3G/HD/SD-SDI Serializers

Semtech GS2972 3G/HD/SD-SDI Serializers generate an SMPTE ST 424, SMPTE ST 292, SMPTE ST 259-C, or DVB-ASI compliant serial digital output signal. The integrated Narrow BW PLL allows the device to accept parallel clocks with high input jitter. The devices provide an SMPTE-compliant serial digital output. The device can operate in four basic user-selectable modes: SMPTE mode, DVB-ASI mode, data-through mode, or standby mode.
