■ GENERAL DESCRIPTION
designed for data communications. It is particularly well suited for FSK modem
applications, and operates over a wide frequency range of 0.01Hz to 300kHz. It
can accommodate analog signals between 2mV 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 independently set carrier frequency, bandwidth, and output delay.
