NOTES
1Temperature range (T
MIN to TMIN); 0°C to +70°C.
2Sample tested at +25
°C to ensure compliance.
3TTL input values are 0 to 3 volts, with input rise/fall times
≤3 ns, measured between the 10% and 90% points. 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 = 37.5
, CL = 10 pF; RSET = 560
.
ISYNC connected to I0G. All Specifications TMIN to TMAX
1 unless otherwise noted.)
