Figure 1. LVCMOS Output Measurement Setup
Note 2:
Guaranteed up to 320MHz for LVPECL output.
Note 3:
Guaranteed up to 160MHz for LVCMOS output.
Note 4:
All outputs enabled and unloaded. IN_SEL set high.
Note 5:
Measured with crystal or AC-coupled, 50% duty-cycle signal on REF_IN.
Note 6:
Measured using setup shown in Figure 1 with V
CC
= 3.3V ±5%.
Note 7:
Measured with crystal source.
Note 8:
Total TIE including random and deterministic jitter. Measured with Agilent DSO81304A 40GS/s real-time oscilloscope
using 2M sample record length.
Note 9:
Measured with 40mV
P-P
, 100kHz sinusoidal signal on the supply.
Note 10: Measured at 156.25MHz output.
Note 11: Measured with 25MHz crystal or 25MHz reference clock at LVCMOS input with a slew rate of 0.5V/ns or greater.
