Timing reference points at 50% for inputs and outputs. See timing notes in Figure 1. 4This includes effects due to clock and data feedthrough as well as RGB analog crosstalk. Specifications subject to change without notice. (VAA = +5 V 5%; VREF = +1.235 V; RL = 3.75 , CL = 10 pF; RSET = 560 . All Specifications TMIN to TMAX 1 unless otherwise noted.) |
