Table 3: Power Supply Requirements Table 4: Control Port Input Levels (TTL/CMOS) Table 5: Signal Input Levels (high-speed signal path) Table 6: Signal Output Levels (high-speed signal path) TERM_CTRL=ON, DRIVE_CTRL=HI NOTES: (1) Mean peak-to-peak amplitude measurement of either true or complement of the differential signal. (2) VCC = VCCP = 2.5V, VEE = 0V. (3) Terminated in 50 Ω to V CC. This termination is used for testing the part, but other terminations are allowed—see Table 9.
