AMAX Stereo Chipset
The MC13027 and MC13122 have been specifically designed for AM
radio which can meet the EIA/NAB AMAX requirements. They are
essentially the same as the MC13022A and MC13025 with the addition of
noise blanking circuitry. The noise blanker consists of a wide band amplifier
with an RF switch for blanking ahead the IF amplifier and a stereo audio
blanker with adjustable delay and blanking times.
Operating Voltage Range of 6.0 V to 10 V RF Blanker with Built–In Wide Band AGC Amplifier Audio Noise Blanker with Audio Track and Hold Mixer Third Order Intercept of 8.0 dBm (115 dBµV) Wide Band AGC Detector for RF Amplifier Local Oscillator VCO Divide–by–4 for Better Phase Noise Buffered Local Oscillator Output at the Fundamental Frequency Fast Stereo Decoder Lock Soft Stereo Blend Signal Quality Detector to Control Variable Q–Notch Filters for Adaptive
