ML3356
Wideband FSK Receiver
Legacy Device: Motorola MC3356
The ML3356 includes Oscillator, Mixer, Limiting IF Amplifier,
Quadrature Detector, Audio Buffer, Squelch, Meter Drive, Squelch
Status output, and Data Shaper comparator. The ML3356 is designed
for use in digital data communciations equipment.
• Data Rates up to 500 kilobaud
• Excellent Sensitivity: – 3 dB Limiting 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
• Operating Temperature Range TA = –40° to +85°C
