New types of cable emulators (Type1, Type3)
• The thoughts of cable emulator
• Use cable meeting the specification to emulate waveform degradation in worst
case
• Add 2 cable emulators
• Type 1
• Is used to emulate standard cable. ISI jitter plays a dominating role
• Corresponds to Cat 1 (less than 742.5Mb/s rate) and Cat 2 (more than
742.5Mb/s rate) cables
• Type 3
• Is used to emulate cables with built-in passive equalizer. The attenuation of
waveform amplitude is larger while ISI is smaller.
• Only define Cat 2(more than 742.5Mb/s rate)
• Reference:
• Type 2 is cable emulator with 270Mb/s and 742.5Mb/s rate used in the
versions no higher than CTS 1.2a
