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 Audio Bandwidth and Whistle Reduction • Signal Quality Detector for AM Stereo • Very Low Distortion Envelope and Synchronous Detectors • Variable Bandwidth IF ORDERING INFORMATION Device Operating Temperature Range Package MC13027DW T40 ° 85 °C SO–20L MC13027P TA = –40 ° to +85°C Plastic DIP MC13122DW TA = –40 ° to +85°C SO–28L MC13122P Plastic DIP Fast AGC Control Audio Blanking Functional Block Diagram Oscillator Buffer Voltage Controlled Oscillator Wide Band AGC AM Detector Automatic Gain Controlled RF Amplifier Pulse Detector ÷4 Mixer IF Amplifier IF Amplifier AGC Shunt Switch Pulse Length Timer Pulse Delay Timer Signal Quality Detector Pilot Detector Decoder Track & Hold Post Detector Filter 450 kHz IF Signal Level 450 kHz Blend cos θ Fast Lock Control Stereo Indicator Lamp Stop–Sense RF AGC Meter Drive Right Audio Left Audio Yes/No I RF Blanking AGC Output To Synthesizer Osc Tank AGC Input RF Input RF Input L R Q Fast/ Slow MC13027 MC13122 This device contains 428 active transistors.
