[ TXS0102 ] Level Translator for MDC and MDIO

Hi,

Can you suggest the solution of level translating application for MDIO and MDC signals?

Side-A: 3.3V
Side-B: 2.5V

Since my customer is automotive, so I don't have many options.

SN74AVC2T45-Q1
Automotive Dual-Bit Dual-Supply Bus Transceiver with Config Voltage Translation and 3-State

SN74LVC2T45-Q1
Automotive Catalog Dual-Bit Dual Supply Transceiver with Configurable Voltage Translation

TXS0102-Q1
Automotive 2-Bit Bidirectional Voltage-Level Translator for Open-Drain and Push-Pull Application

I choose TXS0102, because it seems more like "modern".
Do you have any recommendation and/or comments?

I'm bit concerned that other family such as LSF0108 describe in the datasheet that MDIO and MDC can be supported.
But in the datasheet of TXS0102, there is no descriptions.

Thanks,
Ken

Hi Kenchiro san ,

I would move your post into the voltage translation forum for more support .
do you only need 2 bit translator device which is auto qualified ?

Hi ShreyasRao,

Thank you for your support.
Yes, I need 2 bit voltage translation which can support MDIO and MDC communication.

- Automotive qualified
- 2ch bidirectional
- MDIO and MDC support

Thanks,
Ken

Ken,

TXS0102 would be the only fit.

MDC is uni-directional and push-pull. MDIO is bi-directional and open-drain. The TXS0102 can support both of these interfaces.

Do you have any more information? I would like to know:

VCCA = ?
VCCB = ?
Data Rate = ?
Driving Distance = ?

Best Regards,
Nirav
