Notes:
1. Excluding IMOD. IMOD ≤ 60mA
2. Typical values are under VCC = 3.3V and TA = 25°C.
3. VIDDIN is the voltage required to guarantee a stable logic level. For a logic "1", DIN must be VIDDIN above /DIN. For stable logic "0", DIN must be VIDDIN below /DIN.
4. OUT and /OUT are current outputs. This specification defines the voltage range that the user must guarantee these pins remain within proper operation.

Notes:
1. AC characteristics are guaranteed by design and characterization.
2. IMOD = 40mA, 25Ω resistors each tied from OUT and /OUT to VCC.
3. IMOD = 40mA, 2.5Gbps, 0-1 pattern, BW = 12KHz to 20MHz.
