TI中文支持网Part Number:OPT3101CONFIG-SW
To avoid aliasing, we chose another frequency of 8.57 MHz. However, the crosstalk variations were quite significant each time.

sub_vd_clk_cnt=np.uint16(9999*(5+(deAliasFreq<<1))/6.0)
tg_illumen_start=np.uint16(0*(5+(deAliasFreq<<1))/6.0)
tg_illumen_end=np.uint16(8500*(5+(deAliasFreq<<1))/6.0)
tg_capture_start=np.uint16(9300*(5+(deAliasFreq<<1))/6.0)
tg_capture_end=np.uint16(9800*(5+(deAliasFreq<<1))/6.0)
tg_calc_start=np.uint16(8500*(5+(deAliasFreq<<1))/6.0)

capture_clk_cnt=np.uint16(8600*(5+(deAliasFreq<<1))/6.0)
tg_en=1
why the sub_vd_clk_cnt and tg_calc_end base on 9999 not 12000？
