Note 1: Specifications for Input Voltage Range, LOS Assert/Deassert Levels, and CML Output Voltage refer to the total differential
peak-to-peak signal applied or measured. PECL output voltages are absolute (single-ended) voltages measured at a single
output.
Note 2: Input edge speed is controlled using four-pole, lowpass Bessel filters with bandwidth approximately 75% of the maximum
data rate.
Note 3: Deterministic jitter is measured with a K28.5 pattern (0011 1110 1011 0000 0101). Deterministic jitter is the peak-to-peak
deviation from ideal time crossings, measured at the zero-level crossings of the differential output per ANSI X3.230,
Annex A.
Note 4: Random jitter is measured with the minimum input signal applied after filtering with a four-pole, lowpass, Bessel filter (fre-
quency bandwidth at 75% of the maximum data rate). For Fibre Channel and Gigabit Ethernet applications, the peak-to-
peak random jitter is 14.1-times the RMS random jitter.
Note 5: Input signal applied after a 933MHz Bessel filter.
Note 6: Input signal applied after a 1.8GHz Bessel filter.
Note 7: Input for LOS assert/deassert and hysteresis tests is a repeating K28.5 pattern. Hysteresis is defined as:
20log (VLOS-DEASSERT / VLOS-ASSERT).
Note 8: Response time to a 10dB change in input power.
