Timing
Type Description
Synchronous
with PCLK1
~ PCLK3
Output
TIMING SIGNAL OUTPUT
Signal levels are LVCMOS/LVTTL compatible.
Selectable timing output.
Selectable from: H sync; H blanking; V sync; V blanking; F sync; F
digital; Display Enable; 10 field ID (film cadence); AFS video/audio
timing (GS4901B only); USER_1~4.
See Section 1.5 on page 23 for signal descriptions.
NOTE: Default output is H blanking.
The current drive capability of this pin may be set high or low via
designated registers in the host interface. By default, the current
drive will be low.
This signal will be high impedance when VID_STD[5:0] = 00h.
Synchronous
with PCLK1
