PRODUCTION DATA
The parallel interface complies with standard graphics interface protocol, which includes a vertical sync signal (VSYNC), horizontal sync signal (HSYNC), data valid signal (DATEN), a 24-bit data bus (PDATA_x), and a pixel clock (PCLK). Figure 5-5 shows the relationship of these signals.
VSYNC must remain active at all times. If VSYNC is lost, the DMD must be transitioned to a safe state. When the system detects a VSYNC loss, it will switch to a test pattern or splash image as specified in flash by the Host.
The parallel interface supports intra-interface bit multiplexing (specified in flash) that can help with board layout as needed. The intra-interface bit multiplexing allows the mapping of any PDATA_x input to any internal data bus bit. When utilizing this feature, each unique input pin can only be mapped to one unique destination bit. The typical mapping is shown in Figure 7-1. An example of an alternate mapping is shown in Figure 7-2.
