ELECTRICAL CHARACTERISTICS (continued)
(See Table 1 for operating conditions. Typical values at VCC = +3.3V, TA = +25°C, unless otherwise noted.)
Note 1:
Measured with 100mVP-P differential amplitude.
Note 2:
Guaranteed by design and characterization.
Note 3:
Measured from the time that the FCTL1 input goes high with FCTL2 = 0 to the time when the supply current drops to less
than 40% of the nominal value.
Note 4:
Measured with PRBS = 231 - 1.
Note 5:
Measurement limited by test equipment.
Note 6:
Jitter tolerance is for BER
≤ 10-12, measured with additional 0.1UI deterministic jitter and 40mVP-P differential input.
Note 7:
Measured with 50kHz to 80MHz SONET filter.
Note 8:
Applies on power-up, after standby.
Note 9:
Over process, temperature, and supply.
Note 10: Hysteresis is defined as 20Log(VLOS-DEASSERT /VLOS-ASSERT).
