PLLGAIN
This register switches the setting of Fmin, Fmax, and Gain of the H-lock PLL VCO.
000: Fmin=60MHz, Fmax=240MHz, Gain=120MHz/V←Standard setting
001: Fmin=Standard, Fmax=Standard-20%, Gain=Standard-22.5%
010: Fmin=Standard-20%, Fmax=Standard, Gain=Standard+2.5%
011: Fmin=Standard-20%, Fmax=Standard-20%, Gain=Standard-20.0%
100: Fmin=Standard+20%, Fmax=Standard+10%, Gain=Standard+8.75%
101: Fmin=Standard+20%, Fmax=Standard-10%, Gain=Standard-13.75%
110: Fmin=Standard, Fmax=Standard+10%, Gain=Standard+11.25%
111: Fmin=Standard, Fmax=Standard-10%, Gain=Standard-11.25%
* After changing the setting, an interval of 3.0ms is required for the H-lock PLL to get
stabilized.
