DATA BULLETIN
MX623
PRELIMINARY INFORMATION
The MX623 is a low-power decoding integrated circuit that measures the frequency of telephone system call progress
tones.
With progress signals input from the telephone line, this single-chip product is programmed to recognize up to thirteen
of the World's most commonly used call-progress frequencies, analyze signal quality, and present the measured result
as a 4-bit parallel data word at the tri-state Data Output.
Using the parallel information from the MX623, the host system, can recognize such call progress information as: ‘Dial’,
‘Busy’, ‘Number Unobtainable’, ‘Ringing’ and Fax/Modem system signals.
This information can then be used in simple or complex applications to control telephone operations. The data output
will require a software format that can analyze the frequency information from the MX623.
Requiring only a single 3.0
volt power supply, the MX623 may be line-powered and will operate under simple logic
or system
μ
Processor control using the 'Data-Change, 'Hold' and 'Chip-Select' functions.
The MX623, whose small size and low power consumption makes it ideal for remote applications, requires a
3.579545MHz telephone system clock or Xtal input, is available in a 16-pin PDIP.
