13. POWER SUPPLY
1)USB OTG SUPPLY
2)DC SUPPLY

14. POWER SUPPLY:
Voltage 5.0 V
Current 500mA (minimum) mA
Connector 2.1mm x 5.5mm Center hot

15. TPS 65950 POWER SUPPLY
The TPS2141 has an integrated 3.3V LDO which is being
used to supply the 3.3V as required on the BeagleBoard for
the DVI-D interface and the UART CALLED WALL SUPPLY.
•  When the DC supply is plugged in, the switch is disabled
because the Ground Is removed from tps 2141.
• TPS 65950 FUNCTIONS
 o Main Core Voltages
• o Peripheral Voltages
• o Power Sequencing

17. POP MEMORY
a MCP (Multi Chip Package) that contains both the SDRAM and
NAND Flash.IT IS MULTI CHIP PACKAGE.

18. SD/MMC CARDS.
The SD/MMC connector is supplied power from the
TPS65950 using the VMMC1 rail
 When a card is inserted into the SD/MMC
connector, the Card Detect pin is grounded.
This is detected on pin P12 of the TPS65950. An
interrupt, if enabled, is sent to the
OMAP3530 via the interrupt pin
 If an SD card is inserted into the SD/MMC connector
and the write protect pin is active,
the Write Detect pin is grounded

19. S-VIDEO CABLE
An S-Video cable can be connected to the BeagleBoard and
from there is can be connected to a TV or monitor that supports
an S-Video input.
IT SUPPORTS NTSC AN PAL FORMAT.
NTSC MEANS “NATIONAL TELIVISION SYSTEM COMMITEE”.
PAL MEANS
It can be changed via the Software.

20. DIFFERENCE BETWEEN NTSC AND PAL:
• NTSC IT USES THE

21. MCBSP

The multi-channel buffered serial port (McBSP) McBSP2 provides a full-duplex direct
serial interface between the OMAP3530 and the audio CODEC in the TPS65950

22. MCBSP1
McBSP1
McBSP1 provides a full-duplex direct serial interface between the OMAP3530 and
the expansion interface. There are 6 signals supported on McBSP1.

23. MCBSP3
McBSP3 provides a full-duplex direct serial interface between the OMAP3530 and the
EXPANSION INTERFACE.

24. DVI-D CABLE

26. RS 232 HEADER:-
In order to access the serial port of the BeagleBoard a flat cable is
required to connect to a PC. The adapter will not plug directly into the
PC and will require an external Female to Female twisted cable (Null
Modem) in order to connect it to the PC. The ribbon cable
is not supplied with the BeagleBoard but can be obtained from
numerous sources.

27. AUDIO CABLES:
A 3.5mm standard stereo output audio jack is provided
to access the stereo output of the onboard audio CODEC.
The Audio CODEC is provided by the TPS65950.
