SM8221
OVERVIEW
The SM8220/SM8221 Calling Number Identification Receiver IC is a CMOS integrated circuit, which provides an interface to various calling information delivery services such as Calling Number Delivery (CND) and Calling Name Delivery (CNAM) patible with the Bellcore GR-30-CORE. The device also contains a power down circuit, a ring detect circuit and a carrier detect circuit for easier system implementation.
