ADF4001BRUZ-R7

ADF4001 clock generator can be used to implement clock sources for PLLs that require very low noise, stable reference signals. It consists of a low noise digital PFD (phase frequency detector), a precision charge pump, a programmable reference divider, and a programmable 13bit N counter. In addition, the 14bit reference counter (R counter) allows selectable REFIN frequencies at the PFD input. A complete PLL (phase-locked loop) can be implemented if the synthesizer is used with an external loop filter and VCO (voltage controlled oscillator) or VCXO (voltage controlled crystal oscillator). The N minimum value of 1 allows flexibility in clock generation. Typical applications are clock generation, low frequency PLLs, low jitter clock source, clock smoothing, frequency translation, SONET, ATM, ADM, DSLAM, SDM.
