DESCRIPTION

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

· Features crystal-less jitter attenuation and internal AMI/B8ZS/HDB3 encoding/decoding.

· Supports G.772 non-intrusive monitoring for enhanced system diagnostics.

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

· Includes controls for independent power down and High-Z in all transmitters.

· Provides reliable data recovery with over 12 dB of cable attenuation and LOS detection compliant with recent specifications.

FEATURES

· Industry-standard footprint and low power consumption.

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

· User-customizable pulse shapes and internal AMI, B8ZS, or HDB3 encoding/decoding.

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

· G.772 Non-Intrusive Monitoring and G.703 BITS Clock Recovery.

· Crystal-less jitter attenuation and serial/parallel microprocessor control interfaces.

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

· Suitable for short-haul E1/T1/J1 line interface applications.
