Datasheet
The LXT300Z and LXT301Z are fully integrated transceivers for both North American 1.544 Mbps (T1) and International 2.048 Mbps (E1) applications. They are pin and functionally compatible with standard LXT300/301 devices, with some circuit enhancements. The LXT300Z provides receive jitter attenuation starting at 3 Hz, and is microprocessor controllable through a serial interface. The LXT301Z is pin compatible, but does not provide jitter attenuation or a serial interface. An advanced transmit driver architecture provides constant low output impedance for both marks and spaces, for improved Bit Error Rate performance over various cable network configurations.
