SN74CBTLV3257: SPI up to 50MHz

Part Number: SN74CBTLV3257


Dear Team,

Can this device support SPI interface up to 50MHz?

If no, please suggest one to replace SN74CBTLV3257PWR

    Hi Kuan,

    For digital applications we recommended the switch bandwidth be 1.5 times the datarate per lane or 3 time the clock frequency per lane.  

    The SN74CBTLV3257  with 200MHz bandwidth should be ok to support SPI up to 50MHz. However, I would also recommend the new TMUX1574 p2p compatible with  SN74CBTLV3257PWR,  also supports SPI signals along with wide operating voltage, high bandwidth, additional features like 1.8-V compatible control inputs, Fail-safe logic.

    Thanks
