[AK1543] AK1543 1300MHz Delta-Sigma Fractional-N Frequency Synthesizer 1. Overview The AK1543 is a Delta-Sigma Fractional-N PLL (Phase Locked Loop) frequency synthesizer with a frequency switching function, covering a wide range of frequencies from 400 to 1300MHz. 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 th.
