Hi All,
I have designed PLL for 6GHz, which is perfectly locking. The question is, when i give "freq" function in cadence simulator calculator for the output frequency it gives the frequency curve over the transient time.(say 0 to 20us). when i see this curve, the frequency is 6G only but it has some +/- variation centered around 6G. The frequency variation is around +/-50Mhz. Is this acceptable?. please suggest me..
