5.4.3 NUMBYTES vs. Minimum / Maximum Jitter Values

Figure 5-2 shows graphically the minimum and maximum allowable jitter values for the NUMBYTES that are

passed in each packet.

FIGURE 5-2 Allowable Jitter Ranges

Table 5-1 correlates the data in a tabular format, with the following notes:

• Minimum jitter buffer depth - The user can specify any non-0 value, but the CSE8 card will select, at mini-

mum, a jitter buffer length of 2 packets (or the equivalent in microseconds) and round up to the nearest 250us.

• Maximum jitter buffer depth - There are limits on the number of packets that can be queued, as well as limits

on the total memory to queue the packets.
