GENERAL DESCRIPTION
The XR-2212 is an ultra-stable monolithic phase-locked
loop (PLL) system especially designed for data
communications and control system applications. Its on
board reference and uncommitted operational amplifier,
together with a typical temperature stability of better than
20ppm/°C, make it ideally suited for frequency synthesis,
FM detection, and tracking filter applications. The wide
input dynamic range, large operating voltage range, large
frequency range, and HCMOS and TTL compatibility
contribute to the usefulness and wide applicability of this
device.

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.
