Table 4C. LVDS DC Characteristics, VDD = 3.3V ± 5%, TA = -40°C to 85°C
AC Electrical Characteristics
Table 5. AC Characteristics, VDD = 3.3V ± 5%, TA = -40°C to 85°C
All parameters measured at
≤ 650MHz unless noted otherwise.
NOTE 1: Measured from VDD/2 of the input to the differential output crossing point.
NOTE 2: Defined as skew between outputs at the same supply voltage and with equal load conditions.
Measured at VDD/2 of the input to the differential output crossing point.
NOTE 3: Defined as skew between outputs on different devices operating at the same supply voltages and with equal load conditions.
Using the same type of inputs on each device, the outputs are measured at the differential cross points.
NOTE 4: This parameter is defined in accordance with JEDEC Standard 65.
