LXT334 General Description

The LXT334 is a quad, short-haul, PCM transceiver for 2.048 MHz or 1.544 MHz transmission systems. Its low impedance transmit output drivers provide constant line impedance whether transmitting marks or spaces. The output pulse amplitudes are also constant, stabilized against supply voltage variations.

The LXT334 can be configured for balanced 100/120 Ω or unbalanced 75 Ω systems and exceeds the latest ETSI return loss recommendations. An on-chip pulse shaping circuit generates accurate transmit pulses independent of the transmit clock duty cycle. All transmitters and receivers incorporate a power down mode with output tri-stating.

The LXT334 features differential receiver architecture with high noise interference margin. It uses peak detection with a variable threshold for reliable recovery of data as low as 500 mV (up to 12 dB of cable attenuation).

The fully digital clock recovery system uses a low frequency master clock of 2.048 MHz or 1.544 MHz as its reference. Each receiver incorporates a combination analog/digital Loss Of Signal (LOS) processor that meets the latest ITU G.775 standard. The LXT334 features a driver failure monitoring circuit in parallel to TTIP and TRING that reports driver shorts.
