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.
