TMS320F28027F: code for initializing quartz clock source

Part Number: TMS320F28027F

Hi,

I'm using the TMS320F28027F and want to use an external quartz as the clock source.

- Is there a list of recommended (and tested) quartz?

- Is there a software example / code snippet how to initialize this setup?

Currently, I'm using this code to use the internal clock source, but I want to change to a more (temperature) stable clock:

//Select the internal oscillator 1 as the clock source and choose frequency
CLK_setOscSrc(myClk, CLK_OscSrc_Internal);
PLL_setClkFreq(myPll, PLL_ClkFreq_60_MHz);
CLK_setLowSpdPreScaler(myClk, CLK_LowSpdPreScaler_SysClkOut_by_4); // 60 MHz SYSCLK -> 60MHz/4 = 15 MHz LSPCLK
