Wideband FSK Receiver
The MC3356 includes Oscillator, Mixer, Limiting IF Amplifier, Quadrature
Detector, Audio Buffer, Squelch, Meter Drive, Squelch Status output, and
Data Shaper comparator. The MC3356 is designed for use in digital data
communciations equipment.
• Data Rates up to 500 kilobaud
• Excellent Sensitivity: – 3 dB Limiting Sensitivity
Excellent Sensitivity: 30 µVrms @ 100 MHz
• Highly Versatile, Full Function Device, yet Few External Parts are
Required
• Down Converter Can be Used Independently — Similar to NE602
