6. 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.
7. In VGA mode, CLK0 minimum pulse duration for clock low should be greater than 4.8 ns. When VGA
switching is to be performed using self-clocked timing, the maximum pixel rate cannot exceed 50 MHz.
8. Reference to CLK0 input only.
8. RCLK is delayed from SCLK in such a way that when RCLK is connected to LCLK, the timing is essentially
the same as the TLC3407x family of parts.
10. This parameter applies when the split shift-register transfer (SSRT) function is enabled (see Section 2.15
for details).
