Dice are designed and guaranteed from -40°C to +85°C but are tested only at T
A
= +25°C.
Supply current measurement excludes the current of the CML output stage (16mA typical). See Figure 1,
Power-Supply
Current Measurement
.
Guaranteed by design and characterization.
Input edge speed is controlled using 4-pole, lowpass Bessel filters with bandwidth approximately 75% of the maximum
data rate.
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.
Random jitter is measured with the minimum input signal. For Fibre Channel and Gigabit Ethernet applications, the peak-
to-peak random jitter is 14.1 times the RMS random jitter.
Power-supply noise rejection (PSNR) is calculated by the equation PSNR = 20log (
V
CC
/(
V
OUT
)), where
V
OUT
is the
change in differential output voltage due to the power-supply noise,
V
CC
. See Power-Supply Noise Rejection vs.
Frequency in the
Typical Operating Characteristics
.
Hysteresis is defined as: 20
log(V
LOS-DEASSERT
/V
LOS-ASSERT
).
Response time to a 10dB change in input power. For the specification guaranteed, the power is assumed to switch back
and forth between two levels (separated by 10dB and equidistant from assert and deassert levels) outside of the two
hysteresis thresholds.
Note 10:
All power-detect AC parameters are guaranteed with a 2

- 1 PRBS, 2.5Gbps input, with the longest possible run of 80CID.
