Notes:
2. VDIF (DC) is the amplitude of the differential HSTL input voltage swing required for device functionality.
3. VX (DC) is the crosspoint of the differential HSTL input signal. Functional operations is obtained when the crosspoint is within the VX (DC) range and the input
swing lies within the VDIF (DC) specification.
4. Equivalent to a termination of 50
Ω to VTT.
5. Capacitance measured at freq. = 1 MHz, DC Bias = 0.9V, and VAC < 100 mV.
