Pin Functions

PIN I/O DESCRIPTION
Y0P, Y0M, Y1P, Y1M, Y2P, Y2M LVDS Out Differential LVDS data outputs.
Outputs are high-impedance when SHTDN is pulled low (de-asserted)
Y3P, Y3M Differential LVDS Data outputs.
Output is high-impedance when SHTDN is pulled low (de-asserted).
Note: if the application only requires 18-bit color, this output can be left open.
CLKP, CLKM Differential LVDS pixel clock output.
Output is high-impedance when SHTDN is pulled low (de-asserted).
D0 – D27 CMOS IN with pulldn Data inputs; supports 1.8 V to 3.3 V input voltage selectable by VDD supply. To connect a graphic source successfully to a display, the bit assignment of D[27:0] is critical (and not necessarily intuitive).
For input bit assignment see Figure 15 to Figure 18 for details.
Note: if application only requires 18-bit color, connect unused inputs D5, D10, D11, D16, D17, D23, and D27 to GND.
CLKIN Input pixel clock; rising or falling clock polarity is selectable by Control input CLKSEL.
SHTDN Device shut down; pull low (de-assert) to shut down the device (low power, resets all registers) and high (assert) for normal operation.
CLKSEL Selects between rising edge input clock trigger (CLKSEL = VIH) and falling edge input clock trigger (CLKSEL = VIL).
VCC Power Supply(1) 3.3 V digital supply voltage
IOVCC I/O supply reference voltage (1.8 V up to 3.3 V matching the GPU data output signal swing)
PLLVCC 3.3 V PLL analog supply
LVDSVCC 3.3 V LVDS output analog supply
GND Supply ground for VCC, IOVCC, LVDSVCC, and PLLVCC.
(1) For a multilayer pcb, it is recommended to keep one common GND layer underneath the device and connect all ground terminals directly to this plane.
