SYSTEM DESCRIPTION
The XR-2212 is a complete PLL system with buffered
inputs and outputs, an internal reference, and an
uncommitted op amp. Two VCO outputs are pinned out;
one sources current, the other sources voltage. This
enables operation as a frequency synthesizer using an
external programmable divider. The op amp section can
be used as an audio preamplifier for FM detection or as a
high speed sense amplifier (comparator) for FSK
demodulation. The center frequency, bandwidth, and
tracking range of the PLL are controlled independently by

external components. The PLL output is directly
compatible with CMOS, HCMOS and TTL logic families
as well as microprocessor peripheral systems.
The precision PLL system operates over a supply voltage
range of 4.5V to 20V, a frequency range of 0.01Hz to
300kHz, and accepts input signals in the range of 2mV to
3V rms. Temperature stability of the VCO is typically
better than 20 ppm/ C with the optimum timing resistor
value.
