M-985-01
Precise Call Progress and
Special Information Tone Generator
Description
The M-985-01 is an integrated circuit precise tone
detector for call progress and special information
tones (SIT), as defined by CCITT.
The use of integrated circuit techniques allows the
M-985-01 to pack the eight filters for call progress
detection into a single 22-pin DIP or a 20-pin SOIC. A
3.58 MHz crystal-controlled time base guarantees
accuracy and repeatability.
The M-985-01 combines the call progress detection of
the M-982-02 and the SIT detection of the M-984-02.
It has an operating voltage range down to 3V. It has
low power consumption under normal operating con-
ditions. A power down (PD) feature is provided to fur-
ther reduce power consumption when inactive.
