Hi team

There are several quesions. Could you support this?

Q1. Could you tell which signal RBC0 would be synchronized?

Q2. According to the datasheet as below, RBC0/RBC1 would be stretched. But are there any chances that RBC0/RBC1 would be shortened?

Q3. Does TLK1201 have same behaviors with TLK1211 regarding the specifications I asked in Q1, Q2?

Hi Takahashi-san,

Q1: I apologize, but your question is not clear to me. Would it be possible to clarify your question?

Q2: Based on the description of RBC0/RBC1, it would not a shortened.

Q3: Regarding Q2, the behavior is the same.

Thanks,

Drew

Hi Drew,

Thanks.

Regarding Q1, RBC0 is ouput from the device. So they assume RBC0 singal is synchronized with a certain signal. So I want to confirm what the certain siganl is. Does this make sense?

Hi Drew,

One more question.

Could you confirm the recommende operating voltage of VDDPLL?

Hi Takahashi-san,

The RBC0 signal is synchronous with the data on RD[9:0].

VDDPLL is 2.5V.

Thanks,

Hi Drew,

Thanks!

Could you please confirm the recommended votage range of VDDPLL?

Hi Takahashi-san,

Unfortunately, the VDDPLL voltage range is not detailed in TLK1211 data sheet. The TLK1221 is a very similar device and specifies that VDDPLL range is the same as VDD range. I expect the same for TLK1211.

Thanks,

Drew
