TLIN2022A-Q1: level shifter for TLIN2022A-Q1

Part Number: TLIN2022A-Q1
Other Parts Discussed in Thread: LSF0108, , SN74LXC8T245

Hi,

We are using TLIN2022A-Q1 on our design. But we found that the IO voltage of TLIN is 2-5V. But our MCU IO is 1.8V voltage. Do you have any recommendation for level shifter that is suitable for TLIN2022A-Q1. Is the LSF0108 capable to do this?

thanks and best regards,

Chaodong,

Looking over the datasheet of the LSF0108, it looks like that would work. However, I am no expert for this device, so I'm looping in Emrys Maier from our voltage translation team to see if he has any more insight.

Regards,

Hello,

It looks like these signals are not changing directions (EN1, EN2, RXD1, RXD2, TXD1, TXD2), so I would recommend to use a translator such as SN74LXC8T245.

Hi Emrys,

We also need one level shifter for RGMII interface. It should translate 1.8V to 3.3V, and the maximum speed for the data signal is 250M symbol rate. Also we need automotive grade part. Do you have any recommendation?

thanks and best regards,
