CMX602A中文资料Calling Line Identifier plus Call Waiting (Type II)数据手册CML Micro规格书

描述 Description

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.
