Kun,

CHx_FIN_SEL can be set to divide the frequency by 1 or 2. As such, it should be included in the calculation, which means that equation 9 is correct. If CHx_FIN_SEL = 1, then equation 2 and 9 are equivalent.

Also, the connectors just give you access to INxA and INxB. You can connect those the same way as you see on the TI design.
