General Description/Product InformationThe MC12040 is a phase–frequency detector intended for use in systemsrequiring zero phase and frequency difference at lock. In combination with avoltage controlled oscillator (such as the MC1648, MC12147, MC12148 orMC12149), it is useful in a broad range of phase–locked loop applications.• Operating Frequency = 80 MHz Typical
