DESCRIPTION
The DS21354/554 Single-Chip Transceiver (SCT) contains all of the necessary functions for connection to E1 lines. The device is an upward compatible version of the DS2153 and DS2154 SCTs. The onboard clock/data recovery circuitry coverts the AMI/HDB3 E1 waveforms to an NRZ serial stream. The DS21354/554 automatically adjusts to E1 22AWG (0.6 mm) twisted–pair cables from 0 to over 2km in length. The device can generate the necessary G.703 waveshapes for both 75 ohm coax and 120 ohm twisted cables.
FEATURES
Complete E1 (CEPT) PCM-30/ISDN-PRI transceiver functionality
Onboard long and short haul line interface for clock/data recovery and
waveshaping
32-bit or 128-bit crystal-less jitter attenuator
Frames to FAS, CAS, CCS, and CRC4 formats
Integral HDLC controller with 64-byte buffers configurable for Sa Bits, DS0 or
sub DS0 operation
Dual two–frame elastic store slip buffers that can connect to asynchronous
backplanes up to 8.192MHz
Interleaving PCM Bus Operation
8–bit parallel control port that can be used directly on either multiplexed or
non–multiplexed buses (Intel or Motorola)
Extracts and inserts CAS signaling
Detects and generates remote and AIS alarms
Programmable output clocks for Fractional E1, H0, and H12 applications
Fully independent transmit and receive functionality
Full access to Si and Sa bits aligned with CRC-4 multiframe
Four separate loopback functions for testing functions
Large counters for bipolar and code violations, CRC4 code word errors, FAS
word errors, and E bits
IEEE 1149.1 JTAG-Boundary Scan Architecture
Pin compatible with DS2154/52/352/552 SCTs
3.3V (DS21354) or 5V (DS21554) supply;low power CMOS
100-pin LQFP package (14mm X 14mm)
