This section defines the TP-121 XGA/Audio Line Transmitter (see section

6.1), and the TP-122 XGA/Audio Line Receiver (see section 6.2).

6.1 Your TP-121 XGA/Audio Line Transmitter

The TP-121 is an XGA/audio stereo line transmitter that receives an XGA

signal and an unbalanced stereo analog audio signal and transmits them

over CAT 5 cable to a TP-122 receiver, converting the unbalanced stereo

analog audio signal to digital audio (S/PDIF) stream before transmitting,

thus preserving the quality of the audio signal. In particular, the TP-121:

• Has a transmission range of more than 300ft (more than 100m), and a

20kHz audio bandwidth with an S/N ratio that exceeds 80dB on the

same transmission range

• Can power or be powered by the receiver over the same CAT 5 cable

• Is 12V DC fed
