The MX602 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 device includes a 'zero-power' ring or line polarity reversal detector, a dual-tone (2130Hz plus 2750Hz) Tone Alert
Signal detector 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 碌C.
It is suitable for 'on-hook' use in systems using Bellcore specifications TR-NWT-000030 and SR-TSV-002476, British
Telecom specifications SIN227 and SIN242, CCA TW/P&E/312, ETSI ETS 300 659-1 and ETS 300 659-2 and Mercury
Communications MNR 19. It is also suitable for 鈥榦ff-hook鈥?use in some of those systems.
The MX602 may be used with a 3.0V to 5.0V supply and is available in the following packages: 16-pin SOIC (MX602DW)
and a 16-pin PDIP (MX602P).
