Frequency divider

BGT24LTR11's frequency divider has two divider ratios, divide by 16 and divide by 8182 which result in output
frequencies of 1.5 GHz and 3 MHz respectively.

8192
Setting the divider to a 3 MHz output will cause the PTAT to consume current. This ratio is usually used only in
case of a software controlled VCO. In this use case, the V
look-up table (LUT), as explained in section 4.3.
