6.8 Typical Characteristics

The typical characteristics shown in this section apply to near-end eye measurements taken at nominal conditions. The eyes

are measured with various pre-channel cable lengths applied at the input or post-channel cable lengths applied at the output

of the TUSB211A as indicated.
