ML13055
Wideband FSK Receiver
Legacy Device: Motorola MC13055
The ML13055 is intended for 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 ML3356, 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 configura-
tion. 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
• Easy Application, Few Peripheral Components
• Operating Temperature Range TA = –40° to +85°C
