technology, the TCM8000 audio processor  
provides a highly integrated solution for voice-  
band signal processing in FM cellular mobile  
and hand-portable telephones. The device  
incorporates the necessary voice and data filters  
as well as ancillary functions, such as microphone  
preamplifiers, a loudspeaker driver, and a CCITT-  
compatible compandor circuit. A simple 3-wire  
serial interface provides digital control over signal  
path switching, muting, and gain adjustment. The  
filter responses can be switched to suit Advanced

(NMT) system requirements. Switched-capacitor techniques are used to implement the filtering functions, and  
appropriate antialiasing and smoothing filters are incorporated in the device.  
In the active mode, the TCM8000 uses less than 14 mA of supply current and can be set into a standby  
configuration, which reduces the supply current to less than 4 mA.  
The TCM8000 is characterized for operation from –25°C to 80°C.  
Caution.These devices have limited built-in protection. The leads should be shorted together or the device placed in conductive foam  
during storage or handling to prevent electrostatic damage to the MOS gates.
