5.6 Switching Characteristics

over operating free-air temperature range (unless otherwise noted)
PARAMETERTEST CONDITIONSMINTYP(1)MAXUNIT
tRDifferential low-to-high transition timeMeasured with a clock-like pattern at 100 MHz, between 20% and 80% of the differential output voltage. Pre-emphasis disabled.
Transition time is measured with fixture as shown in AC Test Circuit, adjusted to reflect the transition time at the output pins.		80ps
tFDifferential high-to-low transition time80ps
tPLHDifferential low-to-high propagation delayMeasured at 50% differential voltage from input to output.0.52ns
tPHLDifferential high-to-low propagation delay0.52ns
tSKPPulse skew(2)|tPHL–tPLH|20ps
tSKOOutput skew(3)(2)Difference in propagation delay among data paths in the same device.200ps
tSKPPPart-to-part skew(2)Difference in propagation delay between the same output from devices operating under identical condition.500ps
tSMMUX switch timeMeasured from VIH or VIL of the mux-control or loopback control to 50% of the valid differential output.1.86ns
(1) Typical parameters measured at VCC = 3.3 V, TA = 25°C. They are for reference purposes and are not production-tested.
(2) Specified by design and characterization using statistical analysis.
(3) tSKO is the magnitude difference in the propagation delays among data paths between switch A and switch B of the same port and similar data paths between port 0 and port 1. An example is the output skew among data paths from SIA_0± to LO_0±, SIB_0± to LO_0±, SIA_1± to LO_1± and SIB_1± to LO_1±. Another example is the output skew among data paths from LI_0± to SOA_0±, LI_0± to SOB_0±, LI_1± to SOA_1± and LI_1± to SOB_1±. tSKO also refers to the delay skew of the loopback paths of the same port and between similar data paths between port 0 and port 1. An example is the output skew among data paths SIA_0± to SOA_0±, SIB_0± to SOB_0±, SIA_1± to SOA_1± and SIB_1± to SOB_1±.
