Arm CoreLink SDK-200 System Design Kit Technical Overview : LPD-500 Low Power Distributor

LPD-500 Low Power Distributor

The LPD-500 Low Power Distributor is a standalone configurable component to distribute Q-Channel interfaces to multiple devices and subsystems.

Q-Channels are used to manage quiescence, in components of the system that allow the clock to be gated off or power to be removed, to save power when not operational.

The LPD-500 can be used as an expander or sequencer. The following figure shows its use as an expander:
