DS100BR410: Usable for M-PHY?

Michael Kurzmann26

Part Number: DS100BR410

Hi,
Can this device be used as a repeater for M-PHY signals as specified in in https://mipi.org/specifications/m-phy

- DC-coupling: the datasheet does not explicitly say AC-coupling, the test circuitry shown and the condition-text in the electrical characteristics does mention it. DC-coupling is needed, as M-PHY defines bus-states, where a static logic level needs to be driven. Plus, the bus data rate can vary between ~600MT to ~8GT.
- interfacing to VML logic possible.
- logic levels up to 620mV differential (non-terminated), common mode at half that voltage.

Further, does this device require external pull-up resistors at the drivers?

Thank you for any information in advance.

This device will almost certainly need AC coupling. The inputs will bias to ~ 2.5V and the output common mode will be ~ 1.0V and will move with the VOD setting.

This device does not use any external pull-ups on the drivers.

Lee

Thanks for the quick reply. I see that the part won't be suitable for my needs.
Do you know of any other part at TI that might cater the needs described above?

Hi Michael,

Sorry, I am not aware of a direct match to your application.

Hi,

MIPI is not based on Ethernet and you need to look for respective standard Phy.
