DESCRIPTION
TK10651 is a noise reduction IC developed mainly for
cordless phones. It is also used for voice and data
communications. It has a built-in compressor circuit to
increase the average modulation level and an expander
circuit to reduce the noise level. The expander restores the
original dynamics of the input signal. The result is a high
quality signal transmission with low noise. Among the
many functions included, analog switching of the input and
output signal is particularly useful in cordless telephones.
Separate data input and output are provided. The audio
signal path can be muted during data transmission. The
signal path used for data transmission bypasses the com-
pressor and expander circuits.
The TK10651 is available in the SSOP-20 (MFP20)
surface mount package.

APPLICATION INFORMATION (CONT.)
EXPANDER INPUT AMPLIFIER
The non-inverting and inverting input pins as well as the
output pins are available, and can be used as a buffer amp
or filter amp. A data signal can be obtained from the output
pin, without passing through the expander. The input level
and amplifier gain should be set to provide 180 mV(rms)
standard level at the data output pin (pin 17). The expander
input amplifier is not DC biased internally, therefore a bias
voltage from the expander's VREF pin (pin 14) should be
used. The maximum allowable load at the output pin is 10
kΩ.

REFERENCE VOLTAGE SOURCE
(PINS 9 AND 14)
Pin 9 is the reference voltage pin for the compressor and
pin 14 is the reference voltage pin for the expander. The
reference voltages are obtained from an internal band gap
reference and used as the bias source for each section.
SWITCH CIRCUIT (PINS 11, 12, and 13)
The compressor's and expander's mute pins and the through
pin (noise reduction is off) are pulled up by internal current
sources, therefore they do not need an external pull up.
Concerning the switching logic, refer to the table in the Test
Circuit section.
