MT88E39中文资料Calling Number Identification Circuit数据手册Microchip规格书

描述 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 202or 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.

特性 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 MT88E41Applications
• 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
