Hi team,

Could you please help to confirm on below problem regarding to ub948, thanks!

1. As the spec show, ub948 single link output condition, the max OLDI Clock is 96MHz. While in bleow application condition, the PCLK range is 192MHz.

Could you please help to check on it?

2. ub948 internal have 1 PLL for both FPD LINK input, or total 2 PLLs, each PLL for one FPD Link input?

Hello Fery,

1. The recommended operating conditions are correct. For "dual link" it is referring to the FPD Link side, not the OLDI side.

2. There are two PLLs, one for each FPD Link.

Best Regards,

Casey

Hi Casey,

For the question 1, means 948 single OLDI output could support max 192MHz PCLK output, right?

Thanks
