Power Supplies
The SAM9G45 Board contains four regulated power supplies:
The outputs of these regulated power supplies
board.
3.3 VDC Supply
1.8 VDC Supply
1.0 VDC Core Supply
1.0 VDC Core UTMI Supply, PLL
The 3.3 VDC Supply is generated by an LTC1765-3.3 chip. It accepts VIN 5 VCC power and outputs a
regulated +3.3 V to most other circuits in the SAM9G45-VB.
The 1.8 VDC Supply (VDDIOM0, VDDIOM1) is generated by an LT1765-1.8. It is powered by VIN
5 VCC power and outputs a regulated +1.8V.
The 1.0 VDC Core Supply (VDDCORE) is generated by a TPS60500 IC. It is powered by the VIN
5 VCC power.
The 1.0 VDC Core Supply (VDDUTMIC, VDDPLLUTMI and VDDPLLA) is generated by a CMOS
voltage regulator R1100D series. It is powered by the output of the 3.3 VDC Supply.
Note: 1. Corresponding test points (TP1 to TP4, GND) are used with jumpers (JP1.1 to JP7) to
permit probing of these voltages.
