Driver Performance Monitor (DPM) Tx and Rx Jitter Attenuator Single rail 3.3V supply with 5V tolerant inputs Superior crystal-less jitter attenuator Cortina HPS for 1 to 1 protection without relays HDB3, B8ZS, or AMI line encoder/decoder Analog/digital and remote loopback testing functions LOS per ITU G.775, ETS 300 233 and T1.231 JTAG Boundary Scan test port per IEEE 1149.1 100 pin LQFP package Low power consumption of 150 mW per channel (typical)
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.
