Microchip Technology, Inc. Telecom MT88E45BN1

The MT88E45BN1 is a low power CMOS integrated circuit designed for receiving physical layer signals used in North American Calling Identity Delivery (CID) and Calling Identity Delivery on Call Waiting (CIDCW) services, as well as ETSI and BT Calling Line Identity Presentation (CLIP) applications. It features a 1200 baud Bell 202/CCITT V.23 FSK demodulator and a CAS/DT-AS detector, allowing for effective signal processing in telecommunication systems. This component includes separate differential input amplifiers with adjustable gain for optimal connection to Tip/Ring and telephone hybrid or speech ICs. It supports a selectable 3-wire FSK data interface, enabling data to be processed as a bit stream or through a 1-byte buffer. The device operates with a supply voltage range of 3 to 5V and incorporates power management features, including a full chip power down option. The MT88E45BN1 is suitable for various applications, including CID telephones, fax machines, answering machines, and Computer Telephony Integration (CTI) systems, making it a versatile choice for engineers looking to implement calling identity features in their projects.
