ADAV4601 System Design Document Confidential Information
Rev.1 August 2009 Analog Devices Page 100
PWM OUTPUTS
All PWM Output differential pairs should be matched in length, i.e. PWM1A = PWM1B, PWM2A = PWM2B.
GROUND PLANE
A split ground plane should be used in the layout of the ADAV4601 with the Analog and Digital Grounds connected
underneath the ADAV4601 using a single link. This is to avoid possible ground loop currents in the Analog and
Digital ground planes. Components in an analog signal path should be placed away from the digital ground plane
and vice versa.
