L64733C/L64734 Tuner and Satellite Receiver Chipset
This section includes AC timing information for the L64734. During AC
testing, HIGH inputs are driven to 3.0 V and LOW inputs are driven to
0 V. For transitions between HIGH, LOW, and invalid states, timing
measurements are made at 1.5 V, as shown in Figure 8.
Figure 8
AC Test Load and Waveform for Standard Outputs
For 3-state outputs, timing measurements are made from the point at
which the output turns ON or OFF. An output is ON when its voltage is
greater than 2.5 V or less than 0.5 V. An output is OFF when its voltage
is less than VDD 0.5 V or greater than 0.5 V, as shown in Figure 9.
