General Description

The MT88E39 Calling Number Identification Circuit (CNIC1.1) is a CMOS integrated circuit which provides an interface to calling line information delivery services that utilize 1200 baud Bell 202 or CCITT V.23 FSK data transmission schemes.

The MT88E39 receives and demodulates the FSK signal and outputs the data into a simple dual mode 3-wire serial interface which eliminates the need for an UART.

The MT88E39 is Bellcore, ETSI and NTT patible and can operate in 3 V and 5 V applications.

Key Features

  • 1200 baud Bell 202 and CCITT V.23 Frequency Shift Keying (FSK) demodulation Compatible with Bellcore GR-30-CORE, SR-TSV002476, TIA/EIA-716 and ETSI 300 778-1 High input sensitivity Dual mode 3-wire data interface (Serial FSK data stream or MT88E43 compatible 1 byte buffer) Internal gain adjustable amplifier Carrier detect status output Uses 3.579545 MHz crystal or ceramic resonator 3 to 5 V ±10% s.
