LXT388 - Dual T1/E1/J1 Transceiver Note - Not recommended for new designs

The LXT388 is a multipurpose 3.3V short-haul Pulse Code Modulation (PCM) transceiver for use in either 1.544 Mbps (T1 or J1) or 2.048 Mbps (E1) applications. It incorporates four receivers and two transmitters in a single 100-pin LQFP package. The LXT388 provides the Cortina "Hitless Protection Switching" (HPS) feature and an advanced crystal-less, digital Jitter Attenuator (JA) that meets CTR12/13 and the latest SONET/SDH requirements. You can configure the LXT388 as a dual transceiver with transmit and receive jitter attenuator and driver performance monitor. You can also use the LXT388 as a quad receiver.
