PRELIMINARY
ENHANCED CALLING LINE IDENTIFIER WITH CALL WAITING
KS8630D
BRIEF DESCRIPTION
16-SOP-225
KS8630D is a Low power mixed signal CMOS integrated circuit
for receiving a physical layer signals used in the Calling Line
Identification Presentation (CLIP) of British Telecom system,
the Calling Identity Delivery(CID) of Bellcore system, and
similar evolving systems before the call is put through. It can
also satisfy the requirements of CIDCW (Calling Identity
Delivery on Call Waiting) services including very high precision
detection of CAS (CPE Alerting Signal) tone and the signals
used in similar services when the call has already been put
through.
KS8630D carries out the following features : Ring or Line-reversal detection, CAS ( 2130Hz and 2750Hz) Tone
detection, and 1200-baud FSK demodulation which simultanesouly satisfies the BELL202 and the CCITT ( ITU-T )
V.23 specification. The demodulated data for Caller Identification is transmitted serially to the related u-controller.
KS8630D using a patented digital algorithm to detect demodulated FSK signals and CAS signal detection.
The device also has a built-in Automatic Gain Control circuitry which is capable of very high precision detection of
CAS tone. It is suitable for use in Adjunct Boxes or Feature Phones with CID / CIDCW applications.
