Terminal Functions (TVP3010C and TVP3010M) Continued
TERMINAL
I/O
DESCRIPTION
NAME
NO. (FN)
45, 81
NO. (GA)
M11
DVDD
Digital power. All DVDD terminals must be connected
together.
D(0–7)
36–43
B12, C12,
D11, D12,
E11, E12,
F11, F12
I/O
(TTL
compatible)
MPU interface data bus. Data terminals are used to
transfer data in and out of the register map and
palette/overlay RAM.
FS ADJUST
51
L12
I
Full-scale adjustment. A resistor connected between
FS ADJUST and ground controls the full-scale range
of the DACs.
GND
44, 54,
56, 80
J2, L10,
K10, G11
Ground. All GND terminals must be connected. The
GNDs are connected internally.
HSYNCOUT
46
H12
O
(TTL
compatible)
Horizontal sync output after pipeline delay. For
system mode the horizontal-sync output can be
programmed, but for the VGA mode the output
carries the same polarity as the input.
IOR, IOG, IOB
48, 49, 50
J12, J11,
K12
O
Analog current outputs. These outputs can drive a
37.5-
load directly (doubly terminated 75-
line),
thus eliminating the requirement for any external
buffering.
MUXOUT [SENSE]
63
M7
O
(TTL
compatible)
Multiplexer output control or DAC comparator output
signal. When MUXOUT is configured as a multi-
plexer output control, it is software programmable
through the configuration register. When the
multiplexer control register is set to VGA mode, this
output terminal and corresponding configuration
register bit are set low to indicate to external devices
that the VGA pass-through mode is being used.
Alternatively, SENSE can be configured as the DAC
comparator output. In this case, the SENSE is low
when one or more of the DAC output analog levels is
above the internal comparator reference of 350 mV
50 mV.
P(0–31)

A1, C2, B1,
C1, D2, D1,
E2, E1, F1,
F2, G1, G2,
H1, H2
I
(TTL
compatible)
Pixel input port. The port can be used in various
modes as shown in the multiplexer control register.
All the unused terminals need to be tied to GND.
NOTE 1:
All unused inputs should be tied to a logic level and not be allowed to float.
