DAC Interface Register Definitions
(Continued)
Register name: DAC 3 (06h)
Bit 7
Bit 0
D3–7 D3–6 D3–5 D3–4 D3–3 D3–2 D3–1 D3–0
Bits 7–0: DAC 3. These eight bits determine the output
voltage of DAC 3.
DAC 4 Register (I
2C address 07h)
Register name: DAC 4 (07h)
Bit 7
Bit 0
D4–7 D4–6 D4–5 D4–4 D4–3 D4–2 D4–1 D4–0
Bits 7–0: DAC 4. These eight bits determine the output
voltage of DAC 4.
DC Offset and OSD Contrast Control Register (I
2C ad-
dress 08h)
Register name: DC Offset/OSD Cont. (08h)
Bit 7
Bit 0
RSV
OSDC1
OSDC0
DC2
DC1
DC0
Bits 2–0: DC Offset Control. These three bits determine the
active video DC offset to all three channels.
Bits 4–3: OSD Contrast Control. These two bits determine
the contrast level of the OSD information.
Bits 7–5: Reserved.
Global Video Control Register (I
2C address 09h)
Register name: Global Control (09h)
Bit 7
Bit 0
RSV
0
DCF4
DCF1–3
0
PS
BV
Bit 0:
Blank Video. When this bit is a one, blank the
video output. When this bit is a zero allow normal
video out.
Bit 1:
Power Save. When this bit is a one, shut down
the analog circuits to support sleep mode. When
this bit is a zero enable the analog circuits for
normal operation.
Bit 2:
MUST BE SET TO “0” FOR PROPER OPERA-
TION.
Bit 3:
DAC1–3 Configuration. When this bit is a zero
the DAC outputs of DAC1–3 are full scale
(0V–4.5V). When this bit is 1, the range of
DAC1–3 are halved (0V–2.25V).
Bit 4:
DAC4 Configuration. When this bit is a zero the
DAC4 output is not mixed with the other DAC
outputs. When the bit is one, 50% of the DAC4
output is added to DAC1–3.
Bit 5:
MUST BE SET TO “0” FOR PROPER OPERA-
TION.
Bits 7–6: Reserved.
Increment Mode Register (I
2C address 0Ah)
Register name: Increment Mode (0Ah)
Bit 7
Bit 0
RSV
TST
INCR
Bit 0:
Increment Enable. When set to a “0”, the default
value, the increment mode is enabled. This al-
lows the registers to be updated sequentially by
sending another block of data.
Bit 1:
MUST BE SET TO “0” FOR PROPER OPERA-
TION.
Bits 7–2: Reserved.
Clamp Polarity and Bandwidth (I
2C address 0Bh)
Register name: Clamp/BW (0Bh)
Bit 7
Bit 0
RSV
CLMP
BW1
BW2
BW0
Bits 2–0: Bandwidth. Used to set the bandwidth of the
preamp. The default is 100. When all bits are set
to “1”, the LM1267 will have maximum bandwidth,
when all bits are set to “0” the LM1267 will have
minimum bandwidth.
Bit 3:
Determines the polarity of the clamp signal used
by the LM1267, “0” (default) is a positive clamp
signal, “1” is a negative going clamp signal.
Bits 7–4: Reserved.
Software Reset Register (I
2C address 0Fh)
Register name: Software Reset (0Fh)
Bit 7
Bit 0
RSV
SRST
Bit 0:
Software Reset. Setting this bit causes a software
reset. All registers (except this one) are loaded
with their default values. All operations currently
in progress are aborted (except for I
2C transac-
tions). This bit automatically clears itself when the
reset has been completed.
Bits 7–1: Reserved.
