Hi,
I have a problem with CDCE949 configuration.
I'm trying to configure CDCE949 register via I2C.
The value which I wrote to the register via I2C write operation,
it was never reflected to the register.
I checked the signal of I2C(SDA/SCL) via oscilloscope while I2C write operation.
It seem there are no problem with the signal and the write sequence.
Q1.
Are there any factors to this issue?
Q2.
CDCE949 is supporting I2C Standard and Fast mode.
Which timing is Stand mode or Fast mode of I2C determined?
Is it first shot of the active SCL from I2C Master?
best regards,
g.f.
