Sorry for reply later.

Was input signal ready when you program the Si5338?

Thanks.

Hi Hua,

Was the issue fixed?

Thanks.

Hi

Just post feedback here from SF

ns of propagation delay is a  typo. It's picosecond as unit.
We will update this in datasheet later. 

Thanks.

Hi Doug,

For Si5351A, 132.8356 Hz is not valid. The output must be 2.5kHz to 200MHz.

Thanks.

It works normally when connect PIN.6 (SSEN) to ground.

Hi Hua,

What's the VDD of Si5338 pin 7 and pin 24?

I checked the .h file, and it is correct.

Thanks.

Hi Hua,

Is the issue fixed? If no, I will escalate to support system since it is possible to provided some your design information.

Thanks.

Si534x/7x/8x/9x output normal mode disable state has two choices: Stop High and Stop Low.

1. Stop High means that when the output driver is disabled the plus output will be high and the minus output will be low.

The voltage of the output positive V(Out+) = Vbias + Vpp_se, and the voltage of output negative V(out-) = Vbias - Vpp_se

         2. Stop Low means that when the output driver is disabled the plus output will be low and the minus output will be high.

The voltage of the output positive V(Out+) = Vbias - Vpp_se, and the voltage of output negative V(out-) = Vbias + Vpp_se
