AC ELECTRICAL CHARACTERISTICS
(V
(Notes 3, 4)
Note 3: AC parameters are guaranteed by design and characterization.
Note 4: The MAX3676 is characterized with a PRBS of 2
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(V
Note 7: R
Note 8: Small-signal bandwidth cannot be measured directly.
Note 9: RSSI slope = [V
Note 10: 1UI = 1 unit interval = (622.08MHz)
Note 11: At jitter frequencies <10kHz, the jitter tolerance characteristics exceed the ITU/Bellcore specifications. The low-frequency
Note 12: See Typical Operating Characteristics for worst-case distribution.
