The DS2143Q from Analog Devices is a comprehensive, software-driven E1 framer, functioning as a slave or coprocessor to microcontrollers. It supports E1/ISDN-PRI framing and can be configured to handle CAS, CCS, and CRC4 formats. The device features a parallel control port for quick access, allowing a single micro to manage multiple E1 lines efficiently.
Key features include an onboard two-frame elastic store slip buffer, the ability to extract and insert CAS signaling bits, and programmable output clocks for fractional E1 links and DS0 loopbacks. It also supports Sa data link circuitry and FEBE E-Bit detection, counting, and generation. The DS2143Q meets CCITT G.704, G.706, and G.732 specifications.
This E1 controller operates within a 4.5V to 5.5V supply range, consuming low power at 50 mW. It is available in a 44-pin PLCC package, suitable for surface mount applications. The flexible software orientation allows for design modifications to adapt to future E1 specification changes. The device contains 69 8-bit internal registers for configuration and information retrieval.
The operating voltage for the DS2143Q is between 4.5V and 5.5V.
The DS2143Q is available in a 44-PLCC (J-Lead) package, measuring 16.59x16.59.
The DS2143Q operates within a temperature range of 0°C to 70°C.
The DS2143Q supports framing to CAS, CCS, and CRC4 formats.
Key features include an onboard two-frame elastic store slip buffer, extraction/insertion of CAS signaling bits, and programmable output clocks.
