DESCRIPTION

· The CS61884 is a full-featured octal E1/T1/J1 short-haul LIU supporting 1.544 Mbps or 2.048 Mbps data transmission.

· Each channel offers crystal-less jitter attenuation and internal AMI/B8ZS/HDB3 encoding/decoding.

· Channel zero can be configured for G.772 non-intrusive monitoring of other channels.

· Utilizes ultra-low-power, matched-impedance transmitters and receivers for reduced power and superior return loss.

· Internal line matching circuitry minimizes external components.

· Transmitters feature independent power down and High-Z controls.

· Receivers ensure reliable data recovery with over 12 dB cable attenuation and LOS detection.

FEATURES

· Industry-standard footprint.

· Low power consumption.

· No external component changes for 100 Ω/120 Ω/75Ω operation.

· User-customizable pulse shapes.

· Internal AMI, B8ZS, or HDB3 encoding/decoding.

· LOS detection compliant with T1.231, ITU G.775, ETSI 300-233.

· G.772 non-intrusive monitoring.

· G.703 BITS clock recovery.

· Crystal-less jitter attenuation.

· Serial/parallel microprocessor control interfaces.

· Transmitter short circuit current limiter (<50mA).

· TX drivers with fast High-Z and power down.

· JTAG boundary scan compliant with IEEE 1149.1.

· Available in 144-pin LQFP & 160-pin LFBGA packages.

APPLICATIONS
