Wideband FSK Receiver
The MC13055 is intended fo RF data link systems using carrier
frequencies up to 40 MHz and FSK (frequency shift keying) data rates up to
2.0 M Baud (1.0 MHz). This design is similar to the MC3356, except that it
does not include the oscillator/mixer. The IF bandwidth has been increased
and the detector output has been revised to a balanced configuration. The
received signal strength metering circuit has been retained, as has the
versatile data slicer/comparator.
• Input Sensitivity 20 µV @ 40 MHz
• Signal Strength Indicator Linear Over 3 Decades
• Available in Surface Mount Package
• Easy Application, Few Peripheral Components
