NOTES: 5. TTL input signals are 0 to 3 V with less than 3 ns rise/fall time between the 10% and 90% levels unless
otherwise specified. ECL input signals are VDD–1.8 V to VDD–0.8 V with less than 2 ns rise/fall time between
the 20% and 80% levels. For input and output signals, timing reference points are at the 10% and 90% signal
levels. Analog output loads are less than 10 pF. D<0:7> output loads are less than 50 pF. All other output loads
are less than 50 pF unless otherwise specified.
6. In VGA mode, CLK0 minimum pulse duration for clock low should be greater than 4.8 ns.
7. This parameter applies when the split shift register transfer (SSRT) function is enabled. See Section 2.9.1
for details.
