GENERAL DESCRIPTION
The XR-2211A is a monolithic phase-locked loop (PLL)
system especially designed for data communications
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
300kHz. It can accommodate analog signals between
10mV 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 FSK voltage comparator which
provides FSK demodulation. External components are
used to independently set center frequency, bandwidth,
and output delay. An internal voltage reference
proportional to the power supply is provided at an output
pin.
The XR-2211A is available in 14 pin packages specified
for commercial temperature ranges.
