The XR-2211A is a phase-locked loop monolithic phase-locked loop (PLL) especially designed for data communication system applications. It is especially suitable for FSK modem applications. It operates over a wide supply voltage range of 4.5 to 20V and a wide frequency range of 0.01Hz to 300kHz. It can accommodate analog signals between 10mV and 3V and can work with traditional DTL, TTL and ECL logic families. The circuit consists of a basic PLL tracking the passband of the input signal, a quadrature phase detector, providing operator detection, and providing FSK voltage comparison for FSK demodulation. Center frequency, bandwidth and output delay are independently set using external components. An internal voltage reference is proportional to the output pin to provide power. The XR-2211A is a 14-pin specified software package with a commercial temperature range.
