DESCRIPTION

The NE568A 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 NE568A is function and pin-compatible with the NE568, requiring only minor changes in peripheral circuitry (see Figure 3).
