Advance Information  
DS5035  
ISSUE 3  
November 1998  
Features  
1200 baud Bell 202 and CCITT V.23 Frequency  
Shift Keying (FSK) demodulation  
Ordering Information  
MT88E39AS 16 Pin SOIC  
-40 to +85 °C  
Compatible with Bellcore GR-30-CORE,  
SR-TSV-002476, TIA/EIA-716 and  
ETSI 300 778-1  
High input sensitivity  
Description  
Dual mode 3-wire data interface (Serial FSK  
data stream or MT88E43 compatible 1 byte  
buffer)  
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.  
Internal gain adjustable amplifier  
Carrier detect status output  
Uses 3.579545 MHz crystal or ceramic  
resonator  
3 to 5V ±10% supply voltage  
Low power CMOS with power down mode  
Direct pin to pin replacement of MT8841 and  
MT88E41  
The MT88E39 is Bellcore, ETSI and NTT compatible  
and can operate in 3V and 5V 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.  
Applications  
Global (North America, Japan, Europe) FSK  
based CID (Calling Identity Delivery) / CLIP  
(Calling Line Identity Presentation)
