Description

The DS3150 performs all the functions necessary for interfacing at the physical layer to DS3, E3, and STS-1 lines. The receiver performs clock and data recovery, B3ZS/HDB3 decoding, and loss-of-signal monitoring. The transmitter encodes outgoing data and drives standards-compliant waveforms onto 75Ω coaxial cable. The jitter attenuator can be mapped into the receive path or the transmit path.
