1 / 78 page  LXT386 QUAD T1/E1/J1 Transceiver Datasheet 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. The LXT386’s differential receiver architecture provides high noise interference margin and is able to work with up to 12 dB of cable attenuation. The digital clock recovery PLL and jitter attenuator are referenced to a low frequency 1.544 MHz or 2.048 MHz clock. The LXT386 incorporates an advanced crystal-less jitter attenuator switchable between the receive and transmit path. The jitter attenuation performance meets the latest international specifications such as CTR12/13. The jitter attenuation performance was optimized for Synchronous Optical NETwork/Synchronous Digital Hierarchy (SONET/SDH) applications. The LXT386 can be configured as a 3 channel transceiver with G.772 compliant non intrusive protected monitoring points. It uses a single 3.3V supply for low power consumption. The constant delay characteristic of the LXT386 JA as well as a power down mode of all transmitters allows the implementation of Hitless Protection Switching (HPS) applications without the use of relays.
