MODE REGISTER 5 MR5 (MR57–MR50)
(Address (SR4-SR0) = 05H)
Mode Register 5 is an 8-bit-wide register. Figure 49 shows the
various operations under the control of Mode Register 5.
MR5 BIT DESCRIPTION
Y-Level Control (MR50)
This bit controls the Y output level on the ADV7172/ADV7173.
If this bit is set (“0”), the encoder outputs SMPTE levels when
configured in PAL mode and Betacam levels when configured in
NTSC mode. If this bit is set (“1”), the encoder outputs Beta-
cam levels when configured in PAL mode and SMPTE levels
when configured in NTSC mode.
UV-Levels Control (MR52–MR51)
These bits control the U and V output levels on the ADV7172/
ADV7173. It is possible to have UV levels with a peak-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 (MR55–MR54)
These bits control the delay or advance of the CLAMP signal in
the front or back porch of the ADV7172/ADV7173. It is pos-
sible to delay or advance the pulse by 0, 1, 2 or 3 clock cycles.
Clamp Delay Direction (MR56)
This bit controls a positive or negative delay in the CLAMP
signal. If this bit is set (“1”), the delay is negative. If it is not 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 posi-
tion. If this bit is set to (“0”), the CLAMP signal is located in
the front porch position.
