• Manufacturer Part Number: MAX3805
• Description: 10.7Gbps Adaptive Receive Equalizer
• Manufacturer: Maxim

ELECTRICAL CHARACTERISTICS (continued)
(Pin 13 (HFPD) and pin 14 (LFPD) are not connected. Typical values are at V
otherwise noted.) (Values at -40°C are guaranteed by design and characterization.)
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.
Note 4: Measured at 10.7Gbps using a pattern of 100 ones, PRBS 2
Note 5: V
Note 6: Guaranteed by design and characterization.
