Electrical Characteristics
4.3.15.4 Synchronous Interface to Dual-Port Smart Displays
Functionality and electrical characteristics of the synchronous interface to dual-port smart displays are
identical to parameters of the synchronous interface. See
TFT LCD Panels, Electrical
4.3.15.4.1
The interface has an 8-bit data bus, transferring a single 8-bit value (Y/U/V) in each cycle. The bits
D7–D0 of the value are mapped to bits LD17–LD10 of the data bus, respectively.

The frequency of the clock DISPB_D3_CLK is 27 MHz (within 10%).
The DISPB_D3_HSYNC, DISPB_D3_VSYNC and DISPB_D3_DRDY signals are active low.
The transition to the next row is marked by the negative edge of the DISPB_D3_HSYNC signal. It
remains low for a single clock cycle.
The transition to the next field/frame is marked by the negative edge of the DISPB_D3_VSYNC
signal. It remains low for at least one clock cycle.
— At a transition to an odd field (of the next frame), the negative edges of DISPB_D3_VSYNC
— At a transition to an even field (of the same frame), they do not coincide.
The active intervals—during which data is transferred—are marked by the DISPB_D3_HSYNC
signal being high.
