ADSP-21565 max CLKIN0 frequency

Hello

The data sheet for the ADSP-21565 specifies that the max CLKIN0 freq is 30MHz, however I would like to ask whether there would be any issues if I was to drive it with at 40MHz (as I have done previous (legitimately) with SHARC DSP processors such as the ADSP-21489. The reason why I would like to do this is that I need to have a 40MHz low jitter clock for driving serial ADCs and DACs, and this would save the need for two separate oscillators (as I have done in the past).

Many thanks
