Octal Short Haul T1/E1/J1 Low Latency Transport Line Interface

PMC-Sierra 

PM4325 OCTLIU ST

Octal Short Haul T1/E1/J1 Low Latency Transport Line Interface

• Generates E1 pulses compliant to G.703

recommendations.

• Provides line outputs that are current

limited and may be tristated for protection

or use in redundant applications.

• Provides a digital phase locked loop for

generation of a low jitter transmit clock

complying with all jitter attenuation, jitter

transfer, and residual jitter specifications

of AT&T TR 62411 and ETSI TBR 12 and

TBR 13.

• Accepts either dual rail or single rail

DS-1/E1 signals or parallel data from the

SBI/SBI TR interface.

• Performs B8ZS or AMI encoding when

processing a single rail or SBI/SBI TR-

sourced DS-1 signal and HDB3 or AMI

encoding when processing a single rail or

SBI/SBI TR-sourced E1 signal.

• Provides a programmable depth FIFO

buffer for jitter attenuation, rate

conversion, and latency optimization in

the transmit path.

GENERAL

• 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 ST devices can

be configured simultaneously from a

single PROM.

• Supports line and system side

diagnostic loopbacks.

• Provides an IEEE 1149.1 (JTAG)

compliant Test Access Port (TAP) and

controller for boundary scan test.

• Implemented in low power 3.3 V

tolerant 1.8/3.3 V CMOS technology.

• Available in a high-density 288-pin

Tape-SBGA package with a -40 °C to

+85 °C Industrial temperature

operating range.

APPLICATIONS

• Metro Optical Access Equipment.

• Edge Router Line Cards.

• Multi-service ATM Switch Line Cards.

• 3G Base Wireless Equipment.

• Digital Private Branch Exchanges

(PBX).

• Digital Access Cross-Connect

Systems (DACS) and Electronic DSX

Cross-Connect Systems (EDSX).
