Note 1: During the power-on-reset time, the LVPECL outputs are held to logic-low (OUTxx = low, OUTxx = high). See the
Power-
On-Reset (POR)
section for more information.
Note 2: LVPECL inputs can be AC- or DC-coupled.
Note 3: For hot-pluggable purposes, the device can receive LVPECL inputs when no supply voltage is applied. Measured with
V
CC
pins connected to GND. See Figure 1.
Note 4: Measured with LVPECL input (V
IH
, V
IL
) as specified.
Note 5: Measured using reference clock input with 550ps rise/fall time (20% to 80%).
Note 6: When input differential swing is below the specified threshold, a clock failure is declared. See Figure 4.
Note 7: LVPECL outputs terminated 50Ω to V
TT

CC
- 2V.
Note 8: Guaranteed by design and characterization.
Note 9: Measured with 50% duty cycle at reference clock input.
Note 10: Measured with 50mV
