AD721 - Analog Devices

AD721 RGB to NTSC/PAL Encoders

RGB to NTSC/PAL Encoders AD720/AD721 (subcarrier amplitude and phase) signals in accordance with either NTSC or PAL standards. These two outputs are also combined to provide a composite video output. All three outputs are available separately at voltages of twice the standard signal levels as required for driving 75 Ω reverse terminated cables. The AD721 al.
