REV. 0
TIMING REGISTER 0 (TR07–TR00)
(Address (SR4–SR0) = 0AH)
Figure 66 shows the various operations under the control of
Timing Register 0. This register can be read from as well as
written to.
TR0 BIT DESCRIPTION
Master/Slave Control (TR00)
This bit controls whether the ADV7194 is in master or slave mode.
Timing Mode Selection (TR01–TR02)
These bits control the timing mode of the ADV7194. These
modes are described in more detail in the Timing and Con-
trol section of the data sheet.
BLANK
Input Control (TR03)
This bit controls whether the
BLANK
input is used to accept
blank signals or whether blank signals are internally generated.
Note: When this input pin is tied high (to 5 V), the input is dis-
abled regardless of the register setting. It, therefore, should be
tied low (to Ground) to allow control over the I
2
C register.
Luma Delay (TR04–TR05)
The luma signal can be delayed by up to 222 ns (or six clock
cycles at 27 MHz) using TR04–05. For further information see
Chroma/Luma Delay section.
Min Luminance Value (TR06)
This bit is used to control the minimum luma output value
by the ADV7194. When this bit is set to a Logic 1, the luma is
limited to 7IRE below the blank level. When this bit is set to (0),
the luma value can be as low as the sync bottom level.
Timing Register Reset (TR07)
Toggling TR07 from low to high and low again resets the inter-
nal timing counters. This bit should be toggled after power-up,
reset or changing to a new timing mode.
TIMING REGISTER 1
(TR17–TR10)
(Address (SR4–SR0) = 0BH)
Timing Register 1 is an 8-bit-wide register.
Figure 67 shows the various operations under the control of
Timing Register 1. This register can be read from as well written
to. This register can be used to adjust the width and position of
the master mode timing signals.
TR1 BIT DESCRIPTION
HSYNC
Width (TR10–TR11)
These bits adjust the
HSYNC
pulsewidth.
T
PCLK
= one clock cycle at 27 MHz.
HSYNC
to
VSYNC
Delay Control (TR13–TR12)
These bits adjust the position of the
HSYNC
output relative to
the VSYNC output.
T
PCLK
= one clock cycle at 27 MHz.
HSYNC
to
VSYNC
Rising Edge Control (TR14–TR15)
When the ADV7194 is in Timing Mode 1, these bits adjust the
position of the
HSYNC
output relative to the
VSYNC
output ris-
ing edge.
T
PCLK
= one clock cycle at 27 MHz.
VSYNC
Width (TR14–TR15)
When the ADV7194 is configured in Timing Mode 2, these bits
adjust the
VSYNC
pulsewidth.
T
PCLK
= one clock cycle at 27 MHz.
HSYNC
to Pixel Data Adjust (TR16–TR17)
This enables the
HSYNC
to be adjusted with respect to the
pixel data. This allows the Cr and Cb components to be swapped.
This adjustment is available in both master and slave timing
modes.
T
PCLK
= one clock cycle at 27 MHz.
