TSB41BA3F-EP: Power sequence question for 1394 cable and host controller.

Part Number: TSB41BA3F-EP
Other Parts Discussed in Thread: TSB82AF15-EP

I am working on a 1394b design using the TSB41BA3F-EP cable transceiver with the TSB82AF15-EP host controller.

The cable transceiver gets power from the 1394 lane power (3.3V), the host controller from a local 3.3V supply

Is there a required power sequence for these two devices?

Thank you

Hi, Dave

For TSB82AF15-EP power sequence, please refer to section 10.3.1 Power-Up/Power-Down Sequencing in its datasheet.

For TSB41BA3F-EP power sequence, please refer to section 13.2.6 Power-Up Reset.

Thanks

David
