11.2 AC Timing
11-4
This section presents AC timing information for the L64105 MPEG-2
Audio/Video Decoder. The timing diagrams in this section illustrate the
clock edges and specific signal edges from which the timing parameters
are measured. These diagrams do not imply any other timing
relationships. For specific information on functional relationships between
the signals, refer to the appropriate functional and signal definition
sections.
During AC testing, HIGH inputs are driven at V
are driven at 0 V. For transitions between HIGH, LOW, and invalid states,
timing measurements are made at 1.5 V, as shown in
test load, C

Output
For 3-state outputs (see
from the point at which the output turns ON or OFF. An output is ON
when its voltage is greater than 2.4 V or less than 0.4 V. An output is
OFF when its voltage is less than 2.4 V or greater than 0.4 V.
