34, 33, 32,
29, 28, 27,
26, 25
I
Parallel interface data input pins, LVCMOS with pulldown.
For 8-bit RED display: DI7 = R7 – MSB, DI0 = R0 – LSB.
DI[15:8]
42, 41, 40,
39, 38, 37,
36, 35
I
Parallel interface data input pins, LVCMOS with pulldown.
For 8-bit GREEN display: DI15 = G7 – MSB, DI8 = G0 – LSB.
DI[23:16]
2, 1, 48, 47,
46, 45, 44,
43
I
Parallel interface data input pins, LVCMOS with pulldown.
For 8-bit BLUE display: DI23 = B7 – MSB, DI16 = B0 – LSB.
Control signal input, LVCMOS with pulldown.
For display or video application: CI1 = Data enable input.
CI1
5
I
Control signal pulse width must be 3 clocks or longer to be transmitted when the Control
signal filter is enabled (CONFIG[1:0] = 01). There is no restriction on the minimum transition
pulse when the control signal filter is disabled (CONFIG[1:0] = 00). The signal is limited to 2
transitions per 130 clocks regardless of the control signal filter setting.
Control signal input, LVCMOS with pulldown.
For display or video application: CI2 = Horizontal sync input.

I
Control signal pulse width must be 3 clocks or longer to be transmitted when the control
signal filter is enabled (CONFIG[1:0] = 01). There is no restriction on the minimum transition
pulse when the control signal filter is disabled (CONFIG[1:0] = 00). The signal is limited to 2
transitions per 130 clocks regardless of the control signal filter setting.
(1) G = Ground, I = Input, O = Output, and P = Power
(2) 1= HIGH, 0 = LOW
