| HT9033 CAS Tone Detector Features * Operating voltage: 3.5V~5.5V * Differential input * Power down control * Bellcore CAS detection (Type II) * 3.58MHz clock input * Low standby current * High sensitivity: -33dBm * Data valid output * 16-pin DIP/SOP package Applications * Feature phone system * Caller ID with Call Waiting * Computer telephony interface products * Analog Display Service Interface (ADSI) General Description The HT9033 is a CPE Alerting Signal (CAS) tone receiver integrated with digital filter/detector and analog front end circuit. The HT9033 using analog filter techniques to achieve very high precision detection for the present of CAS tone. It is ideal for receiving physical layer signal like Bellcores CPE Alerting Signal (Type II caller ID) and similar evolving services like ETS/BT.

This pin is connected to the ring side of the twisted pair wires. Output of OP AMP Reference voltage output, normally 1/2 VDD. A crystal or ceramic resonator should be connected to this pin and X2. This pin may be driven from an external clock source. A crystal or ceramic resonator should be connected to this pin and X1. CAS detection output. Active high. A logic 1 on this pin puts the chip in power down mode. When a logic 0 is on this pin, the chip in power up mode. This is a Schmitt trigger input. Positive power Negative power, ground Analog positive power Analog negative power No connection Absolute Maximum Ratings Voltages are referenced to VSS, except where noted.

The oscillator circuit will be stop. If PDWN pin= 0, CAS detector is activated. CAS Detector Output Signal The output pin DO is CMOS structure. At the normal status (CAS tone is not presence), the DO pin output low. When the CAS tone is detected, the DO pin will output high level.
