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 provides carrier detection,
and an FSK voltage comparator which provides FSK
demodulation. External components are used to indepen-
dently set carrier frequency, bandwidth and output delay.
