Description
The RC2211 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 0.01 Hz to 300 kHz. It can accommodate analog signals between 2 mV 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 pro
