詳細說明
■ GENERAL DESCRIPTIONThe NJM2211 is a monolithic phase-locked loop (PLL) system especially designed for data communications. It is particularly well suited for FSK modem applications, and operates over a wide frequency range of 0.01Hz to 300kHz. It can accommodate analog signals between 2mV and 3V, and can interface with conventional DTL, TTL and ECL logic families. The circuit consists of a basic PLL for tracking an input signal frequency within the passband, a quadrature phase detector which provides carrier detection, and an FSK voltage comparator which provides FSK demodulation. External components are used to independently set carrier frequency, bandwidth, and output delay.■ FEATURES● Wide Operating Voltage (4.5V to 20V)● Wide frequency range (0.01Hz to 300kHz)● DTL / TTL / ECL logic compatibility● FSK demodulation with carrier-detector● Wide dynamic range (2mV to 3Vrms)● Adjustable tracking range (±1% to ±80%)● Excellent temperature stability (20ppm / °C typical)● Package Outline DIP14, DMP14● Bipolar Technology■ APPLICATIONS● FSK demodulation● Data synchronization● Tone decoding● FM detection● Carrier detection
