from where can I get the reference schematics of BCM53286

 I am using BCM53286 in my design as an Fe switch. Can I get a reference schematic or related documents for the same?

Is 3.3v compatible to 2.5V? Do we need to translate 3.3 to 2.5v for MDIO and MDC?

How can we use 3.3V on termination if there is no 3.3V used in the switch?

Hi,

Please find the below comment per your two questions.

1. The MDC, MDIO pins are 3.3V tolerant.

2. I believe you are refer to our application note "CAP-AN102-R" for the backplane design. Please follow the [Backplane Connection/Termination] Figure you attached and follow the [Table1: Termination Bias Requirements] Device BCM53262/M/S.

 

Thanks,

Ryan
