SDIO buffer for SPI

Other Parts Discussed in Thread: TXB0104, TXB0108, SN74AVC4T774

Hi,

I'm looking for a SDIO buffer for SPI with the following specs:

1) 1.8 and 2.5 Volt.

2) Max freq 50MHz

3) 12 channels

Do we have any device fitting the bill? Can the TXB0104 and TXB0108 do the job?

Thanks

The TXB will only support up to 30MHz for 1.8V to 2.5V. Have you looked at the SN74AVC4T774? It is designed with SPI applications in mind.

Bo ,

do you need translation feature to the buffer ?

This is list of buffers /drivers supporting 1.8V and above with 8-16channels and supporting 50Mhz .

Aozer,

where did you find the 30MHz limitation into the datasheet?

Under the Timing Requirements we can see that the max data rate is 60Mbps. This can be approximated to a frequency of 30Mhz.
