Bt8370/8375/8376
Fully Integrated T1/E1 Framer and Line Interface
The Bt8370/8375/8376 is a family of single chip transceivers for T1/E1 and Integrated
Service Digital Network (ISDN) primary rate interfaces, operating at 1.544 Mbps or
2.048 Mbps. These devices combine a sophisticated framer, transmit and receive slip
buffers, and an on-chip physical line interface to provide a complete T1/E1 transceiver.
The fully featured Bt8370 and short-haul Bt8375 and Bt8376 devices provide a
programmable clock rate adapter for simplifying system bus interfacing. The adapter
synthesizes standard clock signals from the receive or transmit line rate clocks or from an
external reference.
Operations are controlled through memory-mapped registers accessible via a parallel
microprocessor port. Current ANSI, ETSI, ITU-T, and Bellcore standards are supported for
alarm and error monitoring, signaling supervision (e.g., LAPD/SS7), per-channel trunk
conditioning, and Facility Data Link (FDL) maintenance. A serial Time Division Multiplexed
(TDM) system bus interface allows the backplane Pulse Code Modulation (PCM) data
highway to operate at rates from 1.536 to 8.192 Mbps. Extensive test and diagnostic
functions include a full set of digital and analog loopbacks, PRBS test pattern generation,
BER meter, and forced error insertion.
The physical line interface circuit recovers clock and data from analog signals with +3 to
–43 dB cable attenuation, appropriate for both short (–18 dB) and long-haul T1/E1
applications. Receive line equalization (EQ) and transmit Line Build Out (LBO) filters are
implemented using Digital Signal Processor (DSP) circuits for reliable performance. Data
and/or clock jitter attenuation can be inserted on either the receive or transmit path. The
transmit section includes precision pulse shaping and amplitude pre-emphasis for cross
connect applications, as well as a set of LBO filters for long-haul Channel Service Unit
(CSU) applications. A complementary driver output is provided to couple 75/100/120
lines via an external transformer.
