TXB0102: bi-directional level shift for MDIO / SMI

[FAE] Andrew Wang

Part Number: TXB0102
Other Parts Discussed in Thread: TXS0102, LSF0102

Hi Team,

As title, customer needs 2 channel bi-directional level shift for MDIO / SMI, and wants to double check if TXB0102 or TXB0102 is more fit, any suggestion?

Thanks!

The MDIO pull-up resistor is not compatible with TXB devices.

TXS0102 or LSF0102 level shifters should work; see [FAQ] Are there voltage level translation / level shifter device recommendations for the industry standard interfaces like GPIO, SPI, UART, I2C, MDIO, RGMII, I2S etc?
