Note 3: AC parameters are guaranteed by design and characterization.

Note 4: The MAX3675 is characterized with a PRBS of 223 - 1 maintaining a BER of ≤ 10-10 having a confidence level of 99.9%.

Note 5: A lower minimum input voltage of 2mVp-p is achievable; however, the LOP hysteresis is not guaranteed below 3.6mVp-p.

Note 6: Hysteresis = 20log(VRELEASE / VASSERT).

Note 7: Small-signal bandwidth cannot be measured directly.

Note 8: RSSI slope = [VRSSI2 - VRSSI1] / [20log (VID2 / VID1)].

Note 9: 1UI = 1 unit interval = (622.08MHz)-1 = 1.608ns.
