OCTLIU ST
Octal Short Haul T1/E1/J1 Low Latency Transport Line Interface
FEATURES
• 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.
• Uses line rate system clock.
• Monolithic device integrating eight
T1/J1 or E1 short haul line interface
units.
• Software switchable between T1/J1
and E1 operation on a per-device
basis.
• Meets or exceeds T1/J1 and E1 short
haul 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, TBR
4, TBR 12, and TBR 13. In conjunction
with the TEMAP 84 (PM5366), allows
Add Drop Multiplexers and Terminal
Multiplexers to meet GR253, GR496,
and G.783.
• Optional encoding/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 pulse
templates.
• Recovers clock and data using a digital
phase locked loop for high jitter
tolerance.
• Tolerates more than 0.4 UI peak-topeak high frequency jitter as required
by AT&T TR 62411 and Bellcore
TR-TSY-000170.
• Outputs dual rail recovered line pulses,
a single rail DS-1/E1 signal, or parallel
data in SBI/SBI TR bus format.
• Performs B8ZS or AMI decoding when
processing a bipolar DS-1 signal and
HDB3 or AMI decoding when
processing a bipolar E1 signal.
• Detects line code violations (LCVs),
B8ZS/HDB3 line code signatures, and
four (E1), eight (T1+B8ZS), or sixteen
(T1 AMI) successive zeros.
• Provides a programmable depth FIFO
buffer for jitter attenuation, rate
conversion, and latency optimization in
the receive path.
SYSTEM INTERFACE
• Supports transfer of transmitted single
rail PCM and signaling data from
1.544 Mbit/s and 2.048 Mbit/s
backplane buses or a SBI/SBI TR
interface for low pin count
interconnection of up to 11 OCTLIU
STs to the high-density PM5366
TEMAP 84 T1/E1 framer.
RECEIVE SECTION
• Supports T1/E1 signal reception for
distances with up to 12dB of cable
attenuation at nominal conditions using
PIC 22 gauge cable emulation.
• Supports G.772 compliant
non-intrusive protected monitoring
points.
TRANSMIT SECTION
• Generates DSX-1 short haul pulses
with programmable pulse shape
compatible with AT&T, ANSI, and ITU
requirements.

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 TRsourced 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
APPLICATIONS
• 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.
