• Manufacturer: Samsung Semiconductor, Inc.

S5D2650 Data Sheet
Luminance levels produced by the S5D2650 for different broadcast standards (assuming AGCGN=0, CONT=0 and
BRT=0) are summarized in Table 5.
When digital component output is desired in RGB mode, the RGBH register can be programmed to increase the
0-100% values from standard CCIR 601 levels to full range levels.The gain variations are shown in Table 6.
