Install pull-up Rs if AGC pins are
programmed as open-drain
Place filter near BCM3560
EDSAFE_IF_N and EDSAFE_IF_P are
sensitive and should be routed away from
other signals
Route OB_IFVCO_p/n as 200 ohms
differential coplanar lines if possible
OB_IFVCO is 325mVpp single
ended with 100 ohm
Place 100 ohm near BCM3560
Place Rs and Cs near BCM3560
Make the power traces
to U1701 >= 12 mil.
VBUS, GND lines have
high current (500mA),
starting from TPS2052
switch. Make these
traces 12 mil.
Place bypass caps within 200 mils of power pin.
Place bypass caps on topside if possible to avoid a
via. The bypass cap should be physically located
between the power plane and the power pin. Current
should flow from the power plane > capacitor >
power pin.
