Electrical Characteristics
Table 65 shows timing characteristics of signals presented in Figure 63 and Figure 64.
Table 65. Synchronous Display Interface Timing Characteristics (Pixel Level)
ID Parameter Symbol Value Description Unit
IP5 Display interface clock period Tdicp (see
1
) Display interface clock IPP_DISP_CLK ns
IP6 Display pixel clock period Tdpcp DISP_CLK_PER_PIXEL
× Tdicp
Time of translation of one pixel to display,
DISP_CLK_PER_PIXEL—number of pixel
components in one pixel (1.n).
The DISP_CLK_PER_PIXEL is virtual
parameter to define display pixel clock
period.
The DISP_CLK_PER_PIXEL is received by
DC/DI one access division to n
components.
ns
IP7 Screen width time Tsw (SCREEN_WIDTH)
× Tdicp
SCREEN_WIDTH—screen width in,
interface clocks. horizontal blanking
included.
The SCREEN_WIDTH should be built by
suitable DI’s counter
2
.
ns
IP8 HSYNC width time Thsw (HSYNC_WIDTH) HSYNC_WIDTH—Hsync width in DI_CLK
with 0.5 DI_CLK resolution. Defined by DI’s
counter.
ns
IP9 Horizontal blank interval 1 Thbi1 BGXP
× Tdicp BGXP—width of a horizontal blanking
before a first active data in a line (in
interface clocks). The BGXP should be built
by suitable DI’s counter.
ns
IP10 Horizontal blank interval 2 Thbi2 (SCREEN_WIDTH –
BGXP – FW)
× Tdicp
Width a horizontal blanking after a last
active data in a line (in interface clocks)
FW—with of active line in interface clocks.
The FW should be built by suitable DI’s
counter.
ns
IP12 Screen height Tsh (SCREEN_HEIGHT)
× Tsw
SCREEN_HEIGHT— screen height in lines
with blanking.
The SCREEN_HEIGHT is a distance
between 2 VSYNCs.
The SCREEN_HEIGHT should be built by
suitable DI’s counter.
ns
IP13 VSYNC width Tvsw VSYNC_WIDTH VSYNC_WIDTH—Vsync width in DI_CLK
with 0.5 DI_CLK resolution. Defined by DI’s
counter.
ns
IP14 Vertical blank interval 1 Tvbi1 BGYP
× Tsw BGYP—width of first Vertical
blanking interval in line. The BGYP should
be built by suitable DI’s counter.
ns
IP15 Vertical blank interval 2 Tvbi2 (SCREEN_HEIGHT –
BGYP – FH)
× Tsw
Width of second vertical blanking interval in
line. The FH should be built by suitable DI’s
counter.
