Hi Sir,

Currently my customer verification TI device TXB0304RUTR & TXS0104EPWR Fail,

Application 3.3V to 1.8V high speed UART up to 50MHz, Can suggest solution for me ? thanks.

Hi Kuo ,

For high to low translation , you could also consider LSF0204 which can work at 50Mhz given right load caps being less than 30 pf . TXB / TXS doesn't work well at higher frequency .

Kuo,

The Timing Requirements section of the TXB0304 datasheet states that it can support translaton of a 100 Mbps signal (i.e. 50 MHz clock) if the channel capacitance does not exceed 100 pF. Do we know the channel capacitance in this application?

Best Regards,
Nirav
