MOTOROLA ANALOG IC DEVICE DATA
. . . 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
VCC = 1.1 V are possible. The MC3374 also includes an on–board voltage
regulator, low battery detection circuitry, a receiver enable allowing a power
down Sleep–Mode
, 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 = 1.1 to 3.0 Vdc
Low Power Consumption: PD = 1.5 to 5.0 mW
Input Bandwidth 75 MHz
Excellent Sensitivity: 0.5
