BRIEF DESCRIPTION
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.

FEATURES
• CID and CIDCW System Operation
• High Performance CAS Detection and Loop State Tone Alert signal detection
• Internal Automatic Gain Control circuitry for the high precision CAS detection
• Digital Logic FSK demodulator
• Ring or Line-polarity reversal detection
• Low power consumption in standby mode
• 3.58MHz crystal oscillator
• 3.3V ~ 5V Operation
• 16-SOP package ( 225Mil )

APPLICATIONS
• CID / CIDCW Adjunct Boxes and Feature Phones
• A system for British Telecom, Bellcore, CCA
