(11) Typical values represent most likely parametric norms for V
CC
= +3.3V and T
A
= +25°C, and at the Recommended Operation Conditions
at the time of product characterization and are not ensured.
(12) Input Differential Voltage (V
ID
) The DS25BR100 limits input amplitude to 1 volt. The DS25BR101 supports any V
ID
within the supply
voltage to GND range.
(13) Measured on a clock edge with a histogram and an acummulation of 1500 histogram hits. Input stimulus jitter is subtracted
geometrically.
(14) Tested with a combination of the 1100000101 (K28.5+ character) and 0011111010 (K28.5- character) patterns. Input stimulus jitter is
subtracted algebraically.
(15) Measured on an eye diagram with a histogram and an acummulation of 3500 histogram hits. Input stimulus jitter is subtracted.
