The LTC6905's master oscillator has a frequency range spanning 68.9MHz t0 170MHz. A programmable divider extendsthe frequency range from 17.225MHzt0170MHz. Table l describes the recommended frequencies for each divider setting. Note that the ranges overlap; at some frequencies there are two divider/resistor combinations that result in the same frequency. Choosing a higher divider setting will result in less jitter at the expense of slightly higher supply current.
