hi,heiko: This a good solution.And I tested it on RK SOCs.It's work well. On 08/02/2017 12:21 AM, Heiko Stuebner wrote: From: Elaine Zhang Fractional dividers may have special requirements concerning numerator and denominator selection that differ from just getting the best approximation. Fo

From: Elaine Zhang Fractional dividers may have special requirements concerning numerator and denominator selection that differ from just getting the best approximation. For example on Rockchip socs the denominator must be at least 20 times larger than the numerator to generate precise clock fre
