The 7707CVTAxx-2 is a VistaLINK® capable, composite analog video and analog audio fiber transmitter for broadcast quality video and analog audio signals. This single card module accepts one NTSC or PAL analog video input with up to four analog audio inputs, performs analog to digital conversion and transmits them over a single fiber. The companion 7707CVRA Composive Video and Analog Audio Fiber Receiver demultiplexes the signals and converts them back to analog form.
