RE: "Ethernet Tranceiver Out of Production?" Broadcom ethernet BCM5201 VS BCM5221



Hi Jakob.
1. I have not heard anything about the BCM5201 being taken out of production. 
2. The current Ethernet driver will work fine with BCM5221 as well. Yes there
are some differences in the mdio registers but the basic registers are the same and 
only these are used by the driver.
3. We will not replace BCM5201 in the near future.

PS. 5221 and 5201 are NOT 100% pin compatible. You can use the same foot print but
some signals differ and you will need to make preparations for this.

Regards
/Magnus
