1.1 Brief Description
The CMX602A is a low power CMOS integrated circuit for the reception of the physical layer signals used in
BT's Calling Line Identification Service (CLIP), Bellcore's Calling Identity Delivery System (CID), the Cable
Communications Association's Caller Display Services (CDS), and similar evolving systems. It also meets the
requirements of emerging Caller Identity with Call Waiting services (CIDCW).
The device includes a 'zero-power' ring or line reversal detector, a dual-tone (2130Hz plus 2750Hz) Tone Alert
Signal and a 1200-baud FSK V23/Bell202 compatible asynchronous data demodulator with a data retiming
circuit which removes the need for a UART in the associated µController.
It is suitable for use in systems to BT specifications SIN227 and SIN242, Bellcore GR-30-CORE and SR-TSV-
002476, CCA TW/P&E/312, ETSI ETS 300 659 parts 1 and 2, ETS 300 778 parts 1 and 2 and Mercury
