ATS9870 Clause Samples

ATS9870. In 10 MHz PLL external clock mode, the ATS9870 generates a 1 GHz sample clock from an external 10 MHz reference input. The 1 GS/s sample data can be decimated by 1, 2, 4, or any multiple of 10. Call AlazarSetCaptureClock specifying EXTERNAL_CLOCK_10MHz_REF as the clock source and 1 GHz as the sample rate value, and select a decimation of 1, 2, 4, or any multiple of 10 up to 100000. For example, the following code fragment shows how to generate a 250 MS/s sample rate with a 10 MHz external clock input. AlazarSetCaptureClock( handle, // HANDLE –- board handle EXTERNAL_CLOCK_10MHz_REF, // U32 –- clock source Id 1000000000, // U32 –- sample rate Id or value CLOCK_EDGE_RISING, // U32 –- clock edge Id 4 // U32 –- decimation );
