HS 3 I, LVCMOS
w/ pull down 		Horizontal Sync Input Pin
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 6.
VS 4 I, LVCMOS
w/ pull down		 Vertical Sync Input Pin
Video control signal is limited to 1 transition per 130 PCLKs. Thus, the minimum pulse width is 130 PCLKs.
DE 5 I, LVCMOS
w/ pull down 		Data Enable Input Pin
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 6.
PCLK 10 I, LVCMOS
