AD9910 suspension of work

Thread Summary

The user experienced sudden AD9910 chip failure during RAM playback for FM modulation, with registers showing FFFFFFFF. The issue was resolved by addressing the instability of DuPont lines, which caused the reset interface to become disconnected, keeping the reset port high. The user confirmed that the problem was solved after ensuring a stable connection.

Product Number: AD9910

When I was using RAM playback to implement FM modulation, the AD9910 would suddenly stop working after working for several seconds. I added register printing. During normal operation, the printed registers were 0x00, 0x01, 0x02. When it stopped working, the data read was FFFFFFFF, whilch meas the chip has stopped.
My pins:
1、EXT_PWR_DWN: Connected to GND
2、Master_Reset : Connected to FPGA and keep low after init
3、PLL_CLK: When the chip stops functioning, it is very likely to cause a drop!!!
