General Description
MIC2569 is designed to supply power to OpenCable™ systems and CableCARD™ hosts. These CableCARDs are also known as Point of Distribution (POD) cards.
MIC2569 supports both Single and Multiple stream cards through a simple to control parallel interface. All voltage switching is soft-start at turn-on, and break-before-make when changing between different voltage supplies.
