... Positive Power Supply. DD The MT88E43 provides all the features and functions offered by Zarlink’s MT8841 (CNIC), including 1200 baud Bell 202 and CCITT V.23 FSK demodulation. The 3-wire serial data interface provided by CNIC has been enhanced to operate in two modes. In the CNIC compatible mode data transfer is initiated by the device. A second mode allows a microcontroller to extract 8-bit data words from the device. Furthermore, the MT88E43 offers Idle State Tone Alert Signal and line reversal detection capability for BT’ ...
