HS
8
O, LVCMOS Horizontal Sync Output Pin
w/ pull down Video control signal pulse width must be 3 PCLKs or longer to be transmitted when the
Control Signal Filter is enabled. There is no restriction on the minimum transition pulse
when the Control Signal Filter is disabled. The signal is limited to 2 transitions per 130
PCLKs.
See Table 9
VS
7
O, LVCMOS Vertical Sync Output Pin
w/ pull down Video control signal is limited to 1 transition per 130 PCLKs. Thus, the minimum pulse width
is 130 PCLKs.
DE
6
O, LVCMOS Data Enable Output Pin
w/ pull down Video control signal pulse width must be 3 PCLKs or longer to be transmitted when the
Control Signal Filter is enabled. There is no restriction on the minimum transition pulse
when the Control Signal Filter is disabled. The signal is limited to 2 transitions per 130
PCLKs.
See Table 9
PCLK
