TXB0106: Whether it can be used for SDR104 spec in SD card application

user4760726

Part Number: TXB0106
Other Parts Discussed in Thread: TXB0304

Hi team,

One of our customers is looking for SD card buffer/repeater. Their spec is followed SDR104, which clock is up to 208MHz and data is up 104MB/s. Customer is thinking to use TXB series for DATA0~3 & CMD and AUP series for CLK. What do you think? if works, any recommended part?

Best Regards,

Hey Leroy,

Data rates are provided in the data sheet and no this device can not operate at those speeds. We don't have repeater devices in our product line, any device that can handle bi-directional signals provide little to no drive of their own.

Hi , Dylan Hubbard

How about TXB0304 , the data sheet show it can support 140Mbps.

For clock signal , spec is 1.8V at 208MHz , rise time and fall time small than 0.96ns.

thanks!

Hey James,

I think you just answered you own question here, this device can support up to 140 Mbps. 140 Mbps is much less than 208 MHz.
