transmit and receive FIFO buffers.

• Provides a two-frame payload slip
buffer to allow independent backplane
and line timing.

• Automatically generates and transmits
DS-1 performance report mes sages to
ANSI T1.231 and ANSI T1.408
specifications.

• Provides PRBS generators and
detectors on each tributary for error
testing at DS1, E1 and N x 64 Kbit/s
rates as recommende d in IT U-T O.15 1
and O.152.

• Provides an 8-bit microprocessor bus
interface for configuratio n, cont rol, and
status monitoring.

• Uses line ra te system clock.

• Provides an IEEE P1149.1 (JTAG)
compliant test access port (TAP) and
controller for boundary scan test.

• Implemented in a low power 2.5/3.3 V
CMOS technology.

• Available in a hi gh density 208-pin fin e
pitch PBGA (17 mm by 17 mm)
package.

• Provides a -40 °C to +85 °C industrial
temperature operating range.

RECEIVER

• Typical signal recovery of up to -43 dB
at 1024 kHz (E1) and up to -44 dB at
772 kHz (T1/J1).

• Guaranteed minimum signal recovery
of -32 dB at 1024 kHz (E1) and

-36 dB at 772 kHz (T1/J1) using
PIC-22 gauge cable emulation.

• Frames to DSX/DS-1 signals in SF,
and ESF formats.

• Frames to ITU-T G.704 basic and
CRC-4 multiframe formatted E1
signals. The framing procedures are
consistent with ITU-T G.706
specifications.

• Frames to TTC JT-G704 multiframe
formatted J1 signals. Supports the
alternate CRC-6 calculation for
Japanese applications. Frames in the
presence of and detects the Japanese
yellow alarm.

• Tolerates more than 0.4 UI peak-to­peak, high frequency jitter as required
by AT&T TR 62411 and Bellcore TR­TSY-000170.

• Provides programmable in-band
loopback activate and deactivate code
detection.

PM4354 COMET-QUAD

Four Channel Combined E1/T1/J1 Transceiver/Framer

• Provides diagnostic, line and per-DS0
payload loopbacks.

• Extracts up to three HDLC links to an
H-MVIP Bus to support the D-c ha nne l,
for ISDN Primary Rate Interfaces, and
the C-channels, for V5.1/V5.2
interfaces. Detects the V5.2 link
identification signal.

TRANSMITTER

• Generates DS X-1 shorthaul and DS-1
longhaul pulses with programmable
pulse shape compatible with AT&T,
ANSI and ITU requirements.

• Generates E1 pulses compliant to
G.703 recommendations.

• Provides line outputs that are current
limited and may be tristated for
protection or 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 CTR 12 and CTR 13.

• Provides a FIFO buffer for jitter
attenuation and rate conversion in the
transmit path.

• Supports unframed mode and framing
bit, CRC, or data link by-pass.

• Allows insertion of framed or unframed
in-band loopback code sequences.

• Allows insertion of a data link in ESF
mode. Optionally inserts a datalink in
the E1 national use bits.

• Inserts, from an H-MVIP bus, up to
three HDLC links to support the D­channel, for ISDN Primary Rate
Interfaces, and the C-channels, for
V5.1/V5.2 interfaces.

• Transmits TTC JT-G704 multiframe
formatted J1 signals. Supports the
alternate ESF CRC-6 calculation for
Japanese applicati on s.
