PM4323 OCTLIU LT
Octal T1/E1/J1 Low Latency Transport Line Interface Device
• Generates E1 pulses compliant to G.703
recommendations.
• Provides a digitally programmable pulse
shape extending up to five transmitted bit
periods for custom long haul pulse
shaping applications.
• 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.
• 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.
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 LT devices can
be configured simultaneously from a
single PROM.
• Supports line and system side
diagnostic loopbacks.
