Power Management
The KSZ9021GQ offers the following power management modes:
Power Saving Mode
This mode is a KSZ9021GQ green feature to reduce power consumption when the cable is unplugged. It is in effect when
auto-negotiation mode is enabled and the cable is disconnected (no link).
Software Power Down Mode
This mode is used to power down the KSZ9021GQ device when it is not in use after power-up. Power down mode is
enabled by writing a one to register 0h bit 11. In the power down state, the KSZ9021GQ disables all internal functions,
except for the MII management interface. The KSZ9021GQ exits power down mode after writing a zero to register 0h bit
11.
Chip Power Down Mode
This mode provides the lowest power state for the KSZ9021GQ when it is not in use and is mounted on the board. Chip
power down mode is enabled at power-up / reset with the MODE[3:0] strap-in pins set to 0111. The KSZ9021GQ exits
chip power down mode when a hardware reset is applied to RESET_N (pin 110) with the MODE[3:0] strap-in pins set to
an operating mode other than chip power down mode.
