_______________________________________________________________________________________
Note 1: Current into a pin is defined as positive. Current out of a pin is defined as negative. All voltages are referenced to ground
except VTH, VTL, VID, VOD, and
VOD.
Note 2: Maximum and minimum limits over temperature are guaranteed by design and characterization. Devices are 100% tested
at TA = +25°C.
Note 3: Tolerance on all external resistors (including figures) is ±1%.
Note 4: Guaranteed by design and characterization.
Note 5: AC parameters are guaranteed by design and characterization and not production tested. Limits are set at
±6 sigma.
Note 6: CL includes scope probe and test jig capacitance.
Note 7: Pulse-generator output for differential inputs IN_+, IN_- (unless otherwise noted): f = 670MHz, 50% duty cycle, RO = 50
,
tR = 500ps, and tF = 500ps (0% to 100%). Pulse-generator output for single-ended inputs PD, SEL: tR = tF = 1.5ns (0.2VCC
to 0.8VCC), 50% duty cycle, VOH = VCC + 1.0V settling to VCC, VOL = -1.0V settling to zero.
Note 8: Pulse-generator output for tDJ: VOD = 0.15V, VOS = 1.25V, bit rate = 800Mbps, 223 - 1 PRBS, RO = 50
, tR = 500ps, and tF
= 500ps (0% to 100%).
Note 9: tSKPP1 is the magnitude of the difference of any differential propagation delays between devices operating under identical
conditions.
Note 10: tSKPP2 is the magnitude of the difference of any differential propagation delays between devices operating over rated
conditions.
Note 11: Meets all AC specifications.
Note 12: Input jitter subtracted from output jitter.
AC ELECTRICAL CHARACTERISTICS
(VCC = 3.0V to 3.6V, RL = 100
, CL = 5pF, differential input voltage |VID| = 0.15V to 1.2V, MAX9176 input common-mode voltage
VCM = |VID/2| to 2.4V - |VID/2|, MAX9177 input common-mode voltage VCM = |VID/2| to VCC - |VID/2|, TA = -40°C to +85°C, unless oth-
erwise noted. Typical values are at VCC = 3.3V,
|VID| = 0.2V, VCM = 1.25V, TA = +25°C.) (Notes 5, 6, 7)
