ADIS16228 glitch noise on DIO1

Dear ADIer

 

1. If you wirte GLOB_CMD, glitch (20us pulse) occurs on DIO1 pin. Is it normal? The controller recognizes it as an interrupt and generates an error.

2. If you write start (GLOB_CMD [11] = 1) by changing to Automatic FFT (REC_CTRL1 [1: 0] = 01), only one pulse from DIO1 and stops. In my thought, If REC_PRD is 0x0000, the FFT should start automatically every second. But did not start automatically. What is the problem?
