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
