Features

a constant low output impedance transmitter allowing for high transmitter return loss in T1/E1 applications. Transmit pulse shapes (DSX-1 or E1) are selectable for various line lengths and cable types. The LXT304A provides receive jitter attenuation starting at 3 Hz, and is microprocessor controllable through a serial interface. It offers a variety of diagnostic features including transmit and receive monitoring. The device incorporates an onchip crystal oscillator, and also accepts digital clock inputs. It uses an advanced double-poly, double-metal CMOS process and requires only a single 5-vo.
