Description
The DS2143 is a comprehensive, software-driven E1 framer. It is meant to act as a slave or coprocessor to a microcontroller or microprocessor. Quick access through the parallel control port allows a single micro to handle many E1 lines. The DS2143 is very flexible and can be configured into numerous orientations by software. The software orientation of the device allows the user to modify their design to conform to future E1 specification changes. The controller contains a set of 69 8-bit internal registers that the user can access. These internal registers are used to configure the device and obtain information from the E1 link. The device fully meets all of the latest E1 specifications, including CCITT G.704, G.706, and G.732.

Key Features
  • E1/ISDN-PRI framing transceiver
  • Frames to CAS, CCS, and CRC4 formats
  • Parallel control port
  • On-board two frame elastic-store slip buffer
  • Extracts and inserts CAS signaling bits
  • Programmable output clocks for fractional E1 links, DS0 loopbacks, and drop and insert applications
  • On-board Sa-data-link support circuitry
  • FEBE E-bit detection, counting, and generation
  • Pin-compatible with DS2141A T1 controller
  • 5V supply; low power (50mW) CMOS
  • Available in 40-pin DIP and 44-pin PLCC (DS2143Q)
