Product Description ____________________
|
SW136
is
a silicon gate CMOS device containing filters and decoder for detection
of a pair of tones conforming to the DTMF standard with outputs in hexadecimal.
Switched capacitor filter technology is used together with digital circuitry
for the timing control and output circuits.
|
 |
The
circuit provides excellent power line noise and dial tone rejection
and is suitable for applications in central office equipment, PBX, any
key phone systems, remote control equipment and consumer telephony products.
The SW136 monolithic DTMF receiver offers small size, low power consumption
and high performance. It separates the high and low group tones from
the dial up tone pair, verifies the frequencies and duration before
passing the corresponding hexadecimal code to the output. |
