• P600 = 6ns (833 Mbit)
• C400e = 6ns (and 2ns pulse widths [500 Mbit] and less EPA)
• C200e = 20ns (250 Mbit)
X3 is not the maximum compression, but it's most often the best
compromise of the X-modes. For example:
3
• 2 = 8 physical waveform indices for input pins (0,1)
3
• 3 = 27 physical waveform indices for output pins (L, H, X).
X4 and X5 are somewhat problematic because you run out of physical
waveform indices. For example,
4
• 3 = 81 physical waveform indices for output pins (L, H, X) at X4
5
• 3 = 243 physical waveform indices for output pins (L, H, X) at X5
The Agilent 93000 SOC User Training Part 2 (Advanced Digital) covers
the X-modes topic in more detail.
