MOTOROLA RF/IF DEVICE DATA
ELECTRICAL CHARACTERISTICS
(continued)
Compressor/ALC/Tx Mute/Limiter
The compressor analog gound is set to the half supply
reference so the input and output swing capability will
increase as the supply voltage increases. The “C In” input is
ac coupled. The ALC (Automatic Level Control) provides a
soft limit to the output signal swing as the input voltage
increases slowly (i.e., a sine wave is maintained). The Limiter
circuit limits rapidly changing signal levels by clipping the
signal peaks. The ALC and/or Limiter can be disabled
through the MPU serial interface.
(Test Conditions: VCC = 2.6 V, fin = 1.0 kHz, TA = 25
