F
Synchronous
with PCLK
Input
CONTROL SIGNAL INPUT
Signal levels are LVCMOS/LVTTL compatible.
Used to indicate the ODD / EVEN field of the video signal when
DETECT_TRS is set LOW. The device will set the F bit in all outgoing TRS
signals for the entire period that the F input signal is HIGH
(IOPROC_EN/DIS must also be HIGH).
The F signal should be set HIGH for the entire period of field 2 and should
be set LOW for all lines in field 1 and for all lines in progressive scan
systems.
The F signal is ignored when DETECT_TRS = HIGH.
35
V
Synchronous
with PCLK
Input
CONTROL SIGNAL INPUT
Signal levels are LVCMOS/LVTTL compatible.
Used to indicate the portion of the video field / frame that is used for
vertical blanking when DETECT_TRS is set LOW. The device will set the V
bit in all outgoing TRS signals for the entire period that the V input signal is
HIGH (IOPROC_EN/DIS must also be HIGH).
The V signal should be set HIGH for the entire vertical blanking period and
should be set LOW for all lines outside of the vertical blanking interval.
The V signal is ignored when DETECT_TRS = HIGH.
36
H
Synchronous
with PCLK
Input
CONTROL SIGNAL INPUT
Signal levels are LVCMOS/LVTTL compatible.
Used to indicate the portion of the video line containing active video data
when DETECT_TRS is set LOW. The device will set the H bit in all outgoing
TRS signals for the entire period that the H input signal is HIGH
(IOPROC_EN/DIS must also be HIGH).
H signal timing is configurable via the H_CONFIG bit of the
IOPROC_DISABLE register, accessible via the host interface.
Active Line Blanking (H_CONFIG = 0
h
)
The H signal should be set HIGH for the entire horizontal blanking period,
including the EAV and SAV TRS words, and LOW otherwise. This is the
default setting.
TRS Based Blanking (H_CONFIG = 1
h
)
The H signal should be set HIGH for the entire horizontal blanking period
as indicated by the H bit in the received TRS ID words, and LOW
otherwise.
