Features, Applications

. with single conversion circuitry including oscillator, mixer, IF amplifiers, limiting IF circuitry, and quadrature discriminator. The MC3374 is perfect for narrowband audio and data applications to 75 MHz which require extremely low power consumption. Battery powered applications down to VCC 1.1 V are possible. The MC3374 also includes an on­board voltage regulator, low battery detection circuitry, a receiver enable allowing a power down Sleep­Mode TM , two undedicated buffer amplifiers to allow simultaneous audio and data reception, and a comparator for enhancing FSK (Frequency Shift Keyed) data reception to 1200 baud. Low Supply Voltage: VCC to 3.0 Vdc

RF Input CB k Disable Enable 4.7+ VCC VEE 4. CC1 and CC3 are RF coupling capacitors and should have 20 impedance at the desired input and oscillator frequencies. 5. CC2 provides "light coupling" of the oscillator signal into the mixer, and should have 5.0 k impedance at the desired local oscillator frequency. 6. Capacitors labelled CB are bypass capacitors and should have 20 impedance at the desired RF and local oscillator frequencies. 7. The network L1, C1 and C2 provides impedance matching of the mixer input (nominally 3.0 k shunted by 9.0 pF) 50 at the desired RF/IF input frequency. This will allow for bench testing of the receiver from typical RF signal generators or radio service monitors, but additional or different matching will be required to maximize receiver sensitivity when used in conjunction with an antenna, RF preamplifier or mixer.

Data Output NOTES: 1. FL1 and FL2 are 455 kHz ceramic bandpass filters, which should have input and output impedances 2.0 k. Suggested part numbers are MuRata CFW455x ­ the `X' suffix denotes bandwidth. a 455 kHz LC resonator. Recommended part numbers are Toko America or 5SVLC­0637BGT (smaller). The evaluation board layout shown provides for use of either resonator. Ceramic discriminator elements cannot be used with the MC3374 due to their low input impedance. The damping resistor value can be raised to increase the recovered audio or lowered to increase the quadrature detector's bandwidth and linearity ­ practical limits are approximately 75 k. Typically the quadrature detector's bandwidth should match the low IF filter's bandwidth. 3. The data buffer is set as a low­pass filter with a corner frequency of approximately 200 Hz. The audio buffer is a bandpass filter with corner frequencies 300 Hz and 3.0 kHz. The audio amplifier provides bass suppression.
