SMIC 0.18um 1.8v APLL

This IP is a programmable Analog PLL suitable for high speed clock generation. High speed VCO can run from 50MHz to 400MHz. By setting DM [5:0] and DN [7:0] to different values according to different REFIN, CLK will be locked at the multiples of input frequency. Moreover, by adjusting the value of DP [2:0] users can get a lower frequency clock output, CLKO, after CLK is divided by DP [2:0].
