Product Summary
The EM92547BP is a caller ID FSK decoder. It is 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 EM92547BP 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. Applications of the EM92547BP include: adjunct units, answering machines, feature phones, fax machines, computer interface products.
