MC13055 Datasheet, PDF (1/8 Pages) Motorola, Inc – WIDEBAND FSK RECEIVER

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
