GENERAL DESCRIPTION
The XR-2211 is a monolithic phase-locked loop (PLL) system especially designed for data munications applications. It is particularly suited 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 300k Hz. It can acmodate analog signals between 10m V 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...
