LXT386
- Quad T1/E1/J1 Transceiver
Note - Not recommended for new designs
The LXT386 is a quad 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 four transmitters in a single 100-pin LQFP or 160 PBGA package.
The LXT386 provides the Cortina "Hitless Protection Switching" (HPS) feature and an advanced crystal-less Jitter Attenuator (JA) that meets CTR12/13 and the latest SONET/SDH requirements. You can configure the LXT386 as a three-channel transceiver with the additional channel configured as a G.772-compliant nonintrusive performance monitor.
With the introduction of its LXT38x series, Cortina offers a transceiver that supports G.772 nonintrusive performance monitoring. This feature allows one channel to eavesdrop on other channels for remote monitoring and debugging purposes without interrupting service.
