SA568A Datasheet | Philips Semiconductors

Philips Semiconductors Product specification 150MHz phase-locked loop NE/SA568A 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 parison with its predecessor, the NE 568. The NE568A is function and pin-patible with the NE568, requiring only minor changes in peripheral circuitry (see Figure 3). Temperature pensation network is different, no resistor on Pin 12, needs to be grounded and Pin 13 has a 3.9kΩ resistor to ground. Timing cap, C2, is different and for 70MHz operation with temperature...
