AC ELECTRICAL CHARACTERISTICS
(V
(Notes 2, 3)
Note 2: AC parameters are guaranteed by design and characterization.
Note 3: The MAX3676 is characterized with a PRBS of 2
Note 4: A lower minimum input voltage of 2mV
Note 5: Hysteresis = 20log(V
Note 6: R
Note 7: Small-signal bandwidth cannot be measured directly.
Note 8: RSSI slope = [V
Note 9: 1UI = 1 unit interval = (622.08MHz)
Note 10: At jitter frequencies <10kHz, the jitter tolerance characteristics exceed the ITU/Bellcore specifications. The low-frequency
Note 11: See Typical Operating Characteristics for worst-case distribution.
