The CMX602A is a low power CMOS device used for the reception of physical layer signals in Bellcore's

Calling Identity Delivery (CID) and Calling Identity on Call Waiting (CIDCW) systems, British Telecom Calling

Line Identification Service (CLIP), the Cable Communications Association's Caller Display Services (CDS),

and similar evolving services. The CMX602A also meets the requirements of emerging Caller Identity with

Call Waiting Services (CIDCW).

This device includes a 'zero-power' ring or line polarity reversal detector, a dual-tone (2130Hz plus 2750Hz)

internally timed CPE Alerting Signal (CAS) detector, and a 1200-baud FSK Bell202/V23 compatible

asynchronous data demodulator with data retiming circuitry which removes the need for a UART in the

associated µC.

The CMX602A is suitable for use in systems using Bellcore specifications GR-30-CORE and SR-TSV-

002476, British Telecom specifications SIN227 and SIN242, CCA TW/P&E/312, ETSI: ETS 300 659 parts 1

and 2 and ETS 300 778 parts 1 and 2, and Mercury Communications MNR 19.

This device may be used with a 2.7V to 5.5V supply and is available in the following packages:

16-pin SOIC (CMX602AD4) and a 16-pin PDIP (CMX602AP3).
