SLES253 – DECEMBER 2009
Width of negative excursion of tri-level (HDTV mode) or bi-level (SDTV mode) sync
dtg1_spec_b(7:0):
End of active video to 0H
{dtg1_spec_b 0x26(7:0)}
[0101 1000] = [88d]
Distance from end of active video to start of negative sync (SDTV mode) or to negative-to-positive
transition of tri-level sync (HDTV mode)
dtg1_spec_c(7:0):
Positive Hsync width (HDTV)/Equalization pulse (SDTV)
width
{dtg1_spec_c 0x27(7:0)}
[0010 1100] = [44d]
Width of positive excursion of tri-level (HDTV mode). Width of equalization pulses (SDTV mode)
dtg1_spec_d(8:0):
Sync to active video(SDTV)/sync to broad pulse(HDTV)
{dtg1_spec_deh_msb 0x2B(7) and [0 1000 0100] = [132d]
dtg1_spec_d_lsb 0x28(7:0)}
Distance from leading edge of Hsync to start of active video (SDTV mode) or from
negative-to-positive transition of tri-level sync to start of broad pulse (HDTV mode)
dtg1_spec_d1(7:0):
Center equalization pulse to active video (SDTV)
{dtg1_spec_d1 0x29(7:0)}
[0000 0000]
Distance from equalization pulse at center of line to active video (SDTV mode)
dtg1_spec_e(8:0):
Sync to active video (HDTV)/Color bar start (VESA)
{dtg1_spec_deh_msb 0x2B(6) and [0 1100 0000] = [192d]
dtg1_spec_e_lsb 0x2A(7:0)}
Distance from negative-to-positive transition of tri-level sync to start of active video (HDTV mode). In
case color bars are activated in VESA mode, this parameter specifies the start of the color bar with
respect to the horizontal sync
dtg1_spec_h(9:0):
Broad pulse duration (SDTV)
{dtg1_spec_deh_msb 0x2B(1:0)
and
dtg1_spec_h_lsb 0x2C(7:0)}
[00 0000 0000]
Duration of broad pulse (SDTV mode)
dtg1_spec_i(11:0):
Full-line broad pulse duration (SDTV)
{dtg1_spec_i_msb 0x2D(3:0) and [0000 0000 0000]
dtg1_spec_i_lsb 0x2E(7:0)}
Duration of full-line broad pulse (SDTV mode)
dtg1_spec_k(10:0):
End of active video to sync (SDTV)/end of broad pulse to
sync (HDTV)
{dtg1_spec_k_msb 0x30(2:0) and [000 0101 1000] = [88d]
dtg1_spec_k_lsb 0x2F(7:0)}
Distance from end of active video to leading edge of sync (SDTV) or from end of broad pulse to
negative-to-positive transition of tri-level sync (HDTV)
dtg1_spec_k1(7:0):
End of active video in first half of line to center equalization
pulse (SDTV)
