Mnemonic Description
BA1 SDRAM block address signal
WE SDRAM write enable signal
GND Ground
DQ4 SDRAM data line
DQ5 SDRAM data line
DQ2 SDRAM data line
DQ11 SDRAM data line
UDQSN SDRAM upper data strobe compliment signal
SDVDD Memory interface supply
GND Ground
HS_IN1/TRI7 HSync on Graphics Port. The HSync input signal is used for 5-wire timing mode.
This ball can also be used as a trilevel/bilevel input on the SCART or D-terminal
connector.
VS_IN1/TRI8 VS on Graphics Port. The VS input signal is used for 5-wire timing mode. This ball
can also be used as a trilevel/bilevel input on the SCART or D-terminal connector.
GND Ground
TRI3 Digital input capable of slicing bi-level or tri-level input from SCART or D-
Connector.
HS_IN2/TRI5 The HSync input signal is used for 5-wire timing mode. This ball can also be used
as a trilevel/bilevel input on the SCART or D-terminal connector.
VS_IN2/TRI6 The VS input signal is used for 5-wire timing mode. This ball can also be used as a
trilevel/bilevel input on the SCART or D-terminal connector.
GND Ground
TX_PVDD HDMI Tx digital supply (1.8V)
TX_PLVDD HDMI Tx PLL digital supply (1.8V). It is important to ensure that this supply pin has
a clean voltage input.
SDVDD Memory interface supply
A11 SDRAM address line
A6 SDRAM address line
A2 SDRAM address line
CAS SDRAM interface Column Address Select Command Signal. One of four command
signals to the external SDRAM.
RAS SDRAM interface Row Address Select Command Signal. One of four command
signals to the external SDRAM.
VREF Termination reference voltage for memory interface
SDVDD Memory interface supply
LDQSN SDRAM lower data strobe compliment signal
DQ3 SDRAM data line

DQ14 SDRAM data line
GND Ground
SYNC1 This is a synchronization on green or luma input (SOG/SOY) used in embedded
synchronization mode.
AVIN3 Analog video mux input channel
GND Ground
SYNC2 This is a synchronization on green or luma input (SOG/SOY) used in embedded
synchronization mode.
AVIN6 Analog video mux input channel
TRI4 Digital input capable of slicing bi-level or tri-level input from SCART or D-
Connector.
GND Ground
TX_RTERM This signal sets the internal termination resistance. A 470R resistor between this
ball and GND should be used.
TX_VDD33 HDMI Tx PLL Regulator Supply input (3.3V). This pin is an internal voltage
regulator input.
SDVDD Memory interface supply
