The MX633 is a low cost, low power device that uses signal processing techniques to detect audible tone signals such as
Dial, Ringing, Busy and other conditions found when placing a call throughout the world’s telecom systems. Detection of
these call progress stages is essential to the proper operation of automatic calling products.
The MX633 adds new features to Call Progress monitoring. It detects and indicates the ‘U.S. Busy’ tones, reducing the
need to measure ‘tone cadence’ to identify ‘U.S. Busy’. It also detects and indicates voice and other signals from Call
Progress tones, reducing voice-falsing and adding voice-answer as a connection prompt.
The MX633 may be used with a 3.0V to a 5.5V supply and is available in the following package styles: 8-pin PDIP
(MX633P) and 16-pin SOIC (MX633DW).

Notes:
1. For best results, a crystal oscillator design should drive the clock inverter input with signal levels of at least 40% of
VDD, peak to peak. Tuning fork crystals generally cannot meet this requirement. To obtain crystal oscillator design
assistance, consult your crystal manufacturer.
