Tool/software:
Hi,
We use the LMH0387 and can set and read back the mute bit spi address 0: bit 6. However, the video and the SDO/SDO bits keep on swinging.
SPI signals are moving just as illustrated in .pdf. Spi speed is 1MHz, clk resting low, CS set low during bit shift, read back works, bit is second to MSB. Data changing on clk going low, SPI r/w working nice.
Any suggestion for what we could be missing?
The IC has the code 47CE86UH4 LMH0387SL
Best Regards,
Kathy Andersson
