The LXT386 is a quad short haul Pulse Code Modulation (PCM) transceiver for use in both 1.544 Mbps (T1) and 2.048 Mbps (E1) applications. It incorporates four independent receivers and four independent transmitters in a single PBGA-160 or LQFP-100 package. The transmit drivers provide low impedance independent of the transmit pattern and supply voltage variations.The LXT386 transmits shaped waveforms meeting G.703 and T1.102 specifications. The LXT386 exceeds the latest transmit return loss specifications, such as ETSI ETS-300166.
