XR-2211CP RC2211N FSK Demodulator and Tone Decoder DIP-14 The XR-2211 is a monolithic phase-locked loop (PLL) system especially designed for data communications applications. It's particularly suited for FSK modem applications and operates over a wide supply voltage range of 4.5 to 20V and a wide frequency range of 0.01Hz to300kHz. It can accommodate analog signals between10mV 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 within the pass band, a quadrature phase detector which provides carrier detection, and an FSK voltage comparator which provides FSK demodulation. External components are used to independently set center frequency, bandwidth, and output delay. An internal voltage reference proportional to the power supply is provided at an output pin.
