Product Summary

The NE568AD is a monolithic phase-locked loop (PLL) which operates from 1Hz to frequencies in excess of 150MHz and features an extended supply voltage range and a lower temperature coefficient of the VCO center frequency in comparison with its predecessor, the NE 568. The NE568AD is function and pin-compatible with the NE568, requiring only minor changes in peripheral circuitry. The design of the NE568AD is particularly well-suited for demodulation of FM signals with extremely large deviation in systems which require a highly linear output. In satellite receiver applications with a 70MHz IF, the NE568AD will demodulate ±20% deviations with less than 1.0% typical non-linearity. In addition to high linearity, the circuit has a loop filter which can be configured with series or shunt elements to optimize loop dynamic performance. The NE568AD is available in 20-pin dual in-line and 20-pin SO (surface mounted) plastic packages.
