The portfolio of Phase/Frequency Detectors from ON Semiconductor includes high-performance phase frequency-detectors intended for phase-locked loop applications that require a minimum amount of phase and frequency difference at lock. When used in conjunction with high-performance VCO, a high bandwidth PLL can be achieved. The ideal performance characteristics and features of the portfolio include Fully Differential Internally, Temperature Compensation, Open Input Default State, Internal Input Pulldown Resistors, and ESD protection. Phase-frequency detectors from ON Semiconductor meet or exceed the JEDEC Spec EIA/JESD78 IC Latchup Test.
