OCTAL E1/T1/J1 LINE INTERFACE DEVICE

FEATURES

• Monolithic device which integrates eight T1/J1 or E1 short haul and long haul line interface circuits.

• Software switchable between T1/J1 and E1 operation on a per-device basis.

• Meets or exceeds T1/J1 and E1 shorthaul and longhaul network access specifications including ANSI

T1.102, T1.403, T1.408, AT&T TR 62411, ITU-T G.703, G.704 as well as ETSI 300-011, CTR-4, CTR-

12 and CTR-13.

• Provides encoding and decoding of B8ZS, HDB3 and AMI line codes.

• Provides receive equalization, clock recovery and line performance monitoring.

• Provides transmit and receive jitter attenuation.

• Provides digitally programmable long haul and short haul line build out.

• Provides a selectable, per channel independent de-jittered T1 or E1 recovered clock for system timing

and redundancy.

• Provides PRBS generators and detectors on each tributary for error testing at DS1 and E1 rates as

recommended in ITU-T O.151.

• Provides either serial clock/data or parallel Scaleable Bandwidth Interconnect (SBI) interfaces on the

system side.

• Can be configured to act as a converter between the SBI interfaces and serial clock/data. In this

mode, the LIUs are unused.

• Provides an 8-bit microprocessor bus interface for configuration, control, and status monitoring.

• Provides a hardware-only (no microprocessor) mode in which configuration data is read from an SPI-

compatible serial PROM. The PROM interface can be cascaded such that multiple OCTLIU devices

can be configured simultaneously from a single PROM.

• Uses line rate system clock.

• Provides an IEEE 1149.1 (JTAG) compliant Test Access Port (TAP) and controller for boundary scan

test.

• Implemented in a low power 3.3 V tolerant 1.8/3.3 V CMOS technology.

• Available in a high density 288-pin Tape-SBGA (23 mm by 23 mm) package.

• Provides a –40°C to +85°C Industrial temperature operating range.
