TEL : (03) 5787505 FAX : (03) 5779095 Agent : Publication Release Date : EM92547A/B/D CALLER ID FSK DECODER General Description The EM92547 is a single-chip CMOS receiver IC designed to work in telephone equipment incorporating Calling Number Delivery (CND) capabilities.
CND capabilities can be add to equipment such as telephone, adjunct units, answering machines, and facsimile machines, by using the EM92547 and any standard microcontroller IC.
The EM92547 detects and qualifies the incoming ring signal, performs an energy detect on incoming FSK signal, and demodulates the FSK data in accordance with BELL 202 standards.
Integrating the above functions the equipment manufacturer a cost-effective means of implementing CND capabilities into their products.
Features • Compatible with Bellcore GR-30-CORE (formerly as TR-NWT-000030).
• Compatible with British Telecom (BT) SIN227 & SIN242.
• FSK demodulator for Bell 202 and ITU-T V.
23 (formerly as CCITT V.
23) • On-chip ring detector • Ring detect and carrier detect output for MCU interrupt • Power down mode operation • On-chip band pass filter • FSK demodulation with energy detect • High input sensitivity • Low current consumption in power down mode • Single supply from 3.
5V to 6V • Clock Frequencies: 3.
