CMOS-level inputs are converted to analog current outputs that can drive 25–37.5Ω loads corresponding to doublyterminated 50–75Ω loads. A sync current following SYNC input timing is added to the IOG output. BLANK will override RGB inputs, setting IOG, IOB and IOR currents to zero when BLANK = L. Although appropriate for many applications the internal 1.25V reference voltage can be overridden by the VREF input.
