[AK1541] AK1541 20 to 600MHz Delta-Sigma Fractional-N Frequency Synthesizer 1.
Overview The AK1541 is a Delta-Sigma Fractional-N PLL (Phase Locked Loop) frequency synthesizer with a frequency switching function, covering a wide range of frequencies from 20 to 600MHz.
This product consists of an 18-bit Delta-Sigma modulator, a low-noise phase frequency comparator, a highly accurate charge pump, a reference divider and a dual-module prescaler (P/P+1).
An excellent PLL can be achieved by combining
AK1541 Features
* Delta-Sigma Fractional-N frequency synthesizer providing shorter lockup time, lower phase noise and low spurious performance Operating frequency: On-chip charge pump for fast lockup Programmable charge pump current: In a normal operating scheme, the charge pump current can be set in 16 steps
