ADSP21489 PWM: Can it control servos?

I want to control some servos that operate at 50Hz and generate a pulse, with pulse-width ranging from 1 milliseconds to 2 milliseconds. I saw on the HRM of ADSP21489 (on page 8-7) that the minimum switching frequency is 1523Hz for a PCLK of 200MHz. Is there a way to generate a PWM with a period of 20 milliseconds with the PWM channels on the ADSP21489, and if so, how? Is there a prescaler I can set to reduce the switching frequency?
