# Using W5500 alongside Magjack

## Question

Asked by jdcowpland on 2013-10-03 in Ethernet Chips.

Hi,

I’m planning on using a magjack connector alongside a w5500, but am wondering what to do with the center taps. Most other controllers that I’ve come across seem to suggest what to do with them, but the w5500 datasheet doesn’t offer much help in terms of the transformer/rj45 interface. Any help?

Hi, jdcowpland.

There are some product to use, but we are doing aging test for stability. So, after test, we will tell you P/N.
And aging test is taken long period so kindly wait a while.

Best regards.
