Dear Sir
I would like to know what’s different between SWAP/POL=H or L???
Is it mean ,
if SWAP=H ,IN_CLKP will be go through OUT_CLKN and IN_CLKN will be go through OUT_CLKP
If SWAP=L ,IN_CLKP will be go through OUT_CLKP and IN_CLKN will be go through OUT_CLKN
Is it correct ??
Dear Sir
One more question
If i want to use SWAP_EN and LANE_Polarity function at the same time in I2C mode ,Could I do this ??
So Pin mode can't use SWAP_EN and LANE_Polarity function at the same time ,just can select one of mode ,is it correct ??
Hello Kai,
Q1:
if SWAP=H ,IN_CLKP will be go through OUT_CLKN and IN_CLKN will be go through OUT_CLKP
If SWAP=L ,IN_CLKP will be go through OUT_CLKP and IN_CLKN will be go through OUT_CLKN
Is it correct ??
A1:
Yes, that is correct.
When SWAP/POL is high, the n and p pins on each lane will swap and when is low the input lanes swap as per table below.
Q2:
If i want to use SWAP_EN and LANE_Polarity function at the same time in I2C mode ,Could I do this ??
So Pin mode can't use SWAP_EN and LANE_Polarity function at the same time ,just can select one of mode ,is it correct ??
A2:
Yes, according to the device datasheet in order to enable Swap and Polarity functions at the same time you need to set the I2C_EN/PIN and access the 0X09 register. Otherwise, when I2C_EN/PIN=0 you can only selected polarity swap, lanes swap or normal working.
