General Description
The HT9032 calling line identification receiver
is a low power CMOS integrated circuit de-
signed for receiving physical layer signals tran-
smitted according to Bellcore TR-NWT-000030
and ITU-T V.23 specifications. The primary ap-
plication of this device is for products used to
receive and display the calling number, or mes-
sage waiting indicator sent to subscribers from
the central office facilities. The device also pro-
vides a carrier detection circuit and a ring de-
tection circuit for easier system applications.
