OVERVIEW
SM8220/SM8221
Calling Number Identification Receiver IC
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) compatible with the Bellcore
GR-30-CORE. The device also contains a power down cir-
cuit, a ring detect circuit and a carrier detect circuit for eas-
ier system implementation.
