HT9020B
Call Progress Tone Detector
Features
·
·
Operating voltage: 2.5V~5.5V
Good performance:
-8 ~ -39 dBm at VDD=2.5V
0 ~ -27 dBm at VDD=5V
·
Low power consumption
·
Low cost 32768Hz crystal
·
8-pin DIP/SOP packages
·
CPT Band: 305~640Hz detection
General Description
The HT9020B call progress tone detector is a telecom
peripheral for Auto-dialing system use.
When it detected CPT signal then it generates relative
envelopes for external microcontroller decision to finish
different kinds of CPT signal detection such as dial tone,
busy tone, ring-back tone and reorder tone.
Switched capacitors technology is implemented into the
chip to get good performance characteristics of band
pass filter in the range of 305 to 640Hz call progress
tone which is dual tone multi-frequency signal.

HT9020B
Functional Description
The HT9020B call progress tone detector can be used in world wide countries. Below is an illustration of a call progress
tone frequency band, and a table of U.S.A. CPT signal is shown for user reference. Usually, HT9020B must work to-
gether with a microcontroller through software to distinguish correct cadence of CPT to fit any country CPT SPEC re-
quirement for world wide application purposes.
