MC3374

    . . . 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 up to 75 MHz which require extremely low power consumption. Battery powered applications down to V_CC = 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, 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.
