Driving Codec MCLK with C5535 SYSClock configured as USB CLK

Hi, I would like to know if I can use DSP CLKOUT pin configured as USB CLK to drive my codec MCLK. I can also use the SYSCLK (98.304 MHz) with 2 Flip Flop gates to get a 24.576 MHz Ref Clk. My Codec ADC/DAC Fs is rated at 8 KHz, and I know that Codec PLL will be able to reach an exact 8 KHz sampling rate in both situation. I have read on Technical Datasheet (section 1.4.2.3 CLKOUT Pin page 51/556) that glitch may occure when selecting sourve. But in my SW, source will be unique, either SYSCLK with my FF gates or USB CLK, so I think I can do not take into account glich phenomena. I woul like someone to confirm. Thanks. Nicolas
