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.
