Description
|
|
-----------
|
|
|
|
The Broadcom BCM54140 is a Quad SGMII/QSGMII PHY which supports monitoring
|
|
its die temperature as well as two analog voltages.
|
|
|
|
The AVDDL is a 1.0V analogue voltage, the AVDDH is a 3.3V analogue voltage.
|
|
Both voltages and the temperature are measured in a round-robin fashion.
|
