MT88E39 Extended Voltage Calling Number Identification Circuit for CLIP and CID applications (Type 1)
| Product Status - Production |
|
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 compatible and can operate in 3 V and 5 V applications. It is a pin to pin replacement of the MT8841 and MT88E41 by operating in the MT88E41 FSK interface mode (mode 0) when placed in a MT88E41 socket. New designs may also choose the MT88E43 compatible interface (mode 1) where the microcontroller reads the FSK byte from a 1 byte buffer.
Features
- 1200 baud Bell 202 and CCITT V.23 Frequency Shift Keying (FSK) demodulation
- Compatible with Bellcore GR-30-CORE, SR-TSV-002476, 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% supply voltage
- Low power CMOS with power down mode
- Direct pin to pin replacement of MT8841 and MT88E41
Typical Applications
-
Global (North America, Japan, Europe) FSK based CID (Calling Identity Delivery) / CLIP (Calling Line Identity Presentation)
- Feature phones, adjunct boxes
- FAX machines
- Telephone answering machines
- Computer Telephony Integration (CTI)
- Battery powered applications
