Hi team,

Customer is looking the SPI level shift from 1.8V to 3.3V. the speed is over 66Mbps.

Could you please recommend the proper solution to customer? TXB0108 speed is 50Mbps for Vccb 1.8V case.

    SHH,

    We have come out with AXC8T245 with 2 DIR control pins which enable SPI level shifting for 1.8 to 3.3V and upto 380Mbps under std loading.
    with higher loading, the data rate will decrease, however, 66Mbps is low enough to support with AXC8T245.
    There is also SN74AVC4T774 with individual direction control to support 1.8 3.3V SPI interface as well.
    Let me know if this was helpful.
