Interlaced Mode Control (MR47)
This bit is used to setup the output to interlaced or noninterlaced
mode.
MODE REGISTER 5
MR5 (MR57–MR50)
(Address (SR4–SR0) = 05H)
Mode Register 5 is a 8-bit wide register. Figure 55 shows the
various operations under the control of Mode Register 5.
MR5 BIT DESCRIPTION
Y-Level Control (MR50)
This bit controls the component Y output level on the ADV7190/
ADV7191. If this bit is set (0), the encoder outputs Betacam
levels when configured in PAL or NTSC mode. If this bit is
set (1), the encoder outputs SMPTE levels when configured
in PAL or NTSC mode.
UV-Levels Control (MR51–MR52)
These bits control the component U and V output levels on
the ADV7190/ADV7191. It is possible to have UV levels with
a peak-to-peak amplitude of either 700 mV (MR52 + MR51
= 01 ) or 1000 mV (MR52 + MR51 = 10) in NTSC and PAL.
It is also possible to have default values of 934 mV for NTSC
and 700 mV for PAL (MR52 + MR51 = 00).
RGB Sync (MR53)
This bit is used to set up the RGB outputs with the sync infor-
mation encoded on all RGB outputs.
Clamp Delay Value (MR54–MR55)
These bits control the delay or advance of the CLAMP signal
in the front or back porch of the ADV7190/ADV7191. It is pos-
sible to delay or advance the pulse by zero, one, two, or three
clock cycles.
Note: Pin 51 is a multifunctional pin (
VSO
/CLAMP). CLAMP/
VSO
Select Control (MR77) has to be set accordingly.
Clamp Delay Direction (MR56)
This bit controls a positive or negative delay in the CLAMP sig-
nal. If this bit is set (1), the delay is negative. If it is set (0), the
delay is positive.
Clamp Position (MR57)
This bit controls the position of the CLAMP signal. If this bit is
set (1), the CLAMP signal is located in the back porch position.
If this bit is set (0), the CLAMP signal is located in the front
porch position.
