MAX3805
10.7Gbps Adaptive Receive Equalizer
_______________________________________________________________________________________ 3
Note 1: Differential input sensitivity is defined at the input to a transmission line with path length up to 30in.
Note 2: Measured using 10 ones and 10 zeros at 10.7Gbps.
Note 3: Residual jitter is the difference in total jitter between the signal at the input to the transmission line and the equalizer output.
Total residual jitter is DJ P-P + 14.1 × RJ
RMS .
Note 4: Measured at 10.7Gbps using a pattern of 100 ones, PRBS 2 10 - 1, 100 zeros, PRBS 2 10 - 1.
Note 5: V IN = 400mV P-P to 1200mV P-P , input path is 0 to 30in, 6-mil microstrip in FR-4, ε
r = 4.5, and tan δ = 0.02.
Note 6: Guaranteed by design and characterization.
ELECTRICAL CHARACTERISTICS (continued)
(Pin 13 (HFPD) and pin 14 (LFPD) are not connected. Typical values are at V CC = +3.3V, V CC1 = V CC2 = 1.8V, T A = +25 °C, unless
otherwise noted.) (Values at -40°C are guaranteed by design and characterization.)
