LXT336

Quad T1/E1 Receiver

Datasheet

The LXT336 quad receiver is a fully-integrated, quadruple-PCM receiver for both T1 (1.544

Mbps) and E1 (2.048 Mbps) applications. It incorporates four independent receivers in a single

64-pin QFP package.

The LXT336 features a 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 and

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. In addition, each LXT336 receiver incorporates a Loss of Signal

(LOS) detection circuit. The LOS detector is compliant with both ITU-T G.775 and ANSI

T1.231 standards.

The LXT336 ports can be independently configured for either unipolar or bipolar output modes.

HDB3 and AMI decoding mechanisms are available in unipolar mode.
