DS3143 Description

Short technical summary and product information.

The DS3143 is a versatile telecom interface integrated circuit designed by Analog Devices / Maxim Integrated. This device integrates three independent DS3/E3 framers on a single die, capable of framing and formatting for M23 DS3, C-Bit Parity DS3, or G.751 E3 standards.

 

Key features include support for binary (NRZ) or dual-rail (POS/NEG) LIU interfaces, B3ZS/HDB3 encoding/decoding, and the ability to generate and detect DS3/E3 alarms. Each framer is equipped with an integrated HDLC controller, FEAC controller, and Bit Error-Rate Tester (BERT), along with extensive performance monitoring counters and various loopback capabilities.

 

The DS3143 operates within a temperature range of 0°C to 70°C and utilizes a supply voltage between 3.135V and 3.465V, with 5V tolerant I/O. It is housed in a 144-pin, 13mm x 13mm CSBGA package and supports surface mount installation. The 8-bit processor port is compatible with muxed or nonmuxed bus operations for both Intel and Motorola systems. IEEE 1149.1 JTAG support is also included.

 

Applications for the DS3143 include SONET/SDH Muxes, PDH Muxes, Digital Cross-Connect Systems, Access Concentrators, and ATM and Frame Relay Equipment. Its comprehensive feature set makes it suitable for complex telecommunications infrastructure.
