Description
The DS21554LB+ is a single-chip transceiver (SCT) designed for connecting to E1 lines. It is an upgraded version of the DS2153 and DS2154 SCTs, containing all the necessary functions for PCM-30/ISDN-PRI transceiver functionality. With onboard clock/data recovery, integral HDLC controller, and G.703 waveshapes generation for both 75 ohm coax and 120 ohm twisted cables, this device offers complete E1 (CEPT) transceiver functionality. It automatically adjusts to E1 22AWG (0.6 mm) twisted-pair cables of different lengths, making it a versatile solution for various communication scenarios.
Specifications and features
- 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
- Large counters for bipolar and code violations, CRC4 code word errors, FAS word errors, and E bits
- IEEE 1149.1 JTAG-Boundary Scan Architecture
- Low power CMOS with 3.3V (DS21354) or 5V (DS21554) supply
- Pin compatible with DS2154/52/352/552 SCTs
- 100-pin LQFP package (14mm X 14mm)
Application Scenarios
The DS21554LB+ is designed for telecommunication interface ICs. It can be used in various communication scenarios, including E1/CEPT telecommunication systems, ISDN-PRI interfaces, and other applications where PCM-30 traffic is required.
