(1) The requirements in the table apply to all external sources
(2) Vertical Blanking Parameter Definitions:
  1. Vertical Back Porch: Time from the leading edge of VSYNC to the leading edge of HSYNC for the first active line, and includes the VSYNC pulse width tp_vsw.
  2. Vertical Front Porch: Time from the leading edge of HSYNC following the last active line in a frame to the leading edge of VSYNC
  3. Total Vertical Blanking: The sum of VBP + VFP = TVB.
(3) The vertical blanking required (per TVB) can be allocated as desired as long as the VFP and VBP minimum values are met.
(4) The minimum TVB can be calculated using the following:
TVBmin = 11 + ROUNDUP(LLS_VFP_MIN × (Source_ALPF/VPS_ALPF)), where:
  1. LLS_VFP_MIN (Normal Mode) = 22
  2. Source_ALPF = Active Lines Per Frame of the incoming source
  3. VPS_ALPF = 1080 (for 1920x1080 Native products and 3840x2160 4-way XPR products)
  4. Less TVBmin blanking can be required depending on the video processing being done. The configurations that drive the worst case minimum value are those configurations that combine the maximum (or near maximum) capabilities of functions such as scaling, warping, and keystone correction.
  5. This is applicable to all sources (Section 7.4). Other sources require directed testing in the end application.
  6. The minimum recommended TVB with CVT 1.2 sources is 23.
(5) Horizontal Blanking Parameter Definitions:
  1. Horizontal Back Porch: Time from the leading edge of HSYNC to the rising edge of DATEN, and includes the HSYNC pulse width tp_hsw.
  2. Horizontal Front Porch: Time from the falling edge of DATEN to the leading edge of HSYNC.
  3. Total Horizontal Blanking: The sum of HBP + HFP = THB.
(6) The horizontal blanking required (per THB) can be allocated as desired as long as the HFP and HBP minimum values are met.
