Layout Note: place R68 as close as possible to RX_CLKRMI trace and overlap one pad from R13.

This purpose is to not create any stubs coming off the traces. The purpose of the overlap

is to make the two items mutually exclusive.

Place R69 as close as possible to CLKINRMII trace and overlap one pad from C4.

* Note: The (i) designates industrial temperature

LAN8187i PHY (-40c to +85c). For industrial temperature

applications, SMSC recommends using the LAN8187i with

industrial temperature magnetics. For Commercial

temperature magnetics, capacitor C30 and C31 can be

depopulated. Plese refer to APP note 8.13 Magnetics

Selection Guide".
