(1)

Specification is guaranteed by characterization and is not tested in production.

(2)

The Electrical Characteristics tables list guaranteed specifications under the listed Recommended Operating Conditions except as

otherwise modified or specified by the Electrical Characteristics Conditions and/or Notes. Typical specifications are estimations only and

are not guaranteed.

(3)

(5)

(any one input to all outputs).

(6)

(7)

Measured on a clock edge with a histogram and an accumulation of 1500 histogram hits. Input stimulus jitter is subtracted geometrically.

(8)

Tested with a combination of the 1100000101 (K28.5+ character) and 0011111010 (K28.5- character) patterns. Input stimulus jitter is

subtracted algebraically.

(9)

Measured on an eye diagram with a histogram and an accumulation of 3500 histogram hits. Input stimulus jitter is subtracted.
