LVECL/LVPECL 1:15 Differential

Divide-by-1/Divide-by-2 Clock Driver

_______________________________________________________________________________________

Note 1: Measurements are made with the device in thermal equilibrium.

Note 2: Current into a pin is defined as positive. Current out of a pin is defined as negative.

Note 3: Single-ended CLK_, CLK_ input operation is limited to VCC - VEE = 3.0V to 3.8V.

Note 4: DC parameters are production tested at TA = +25°C and guaranteed by design over the full operating temperature range.

Note 5: Use VBB as a reference for inputs of the same device only.

Note 6: All pins open except VCC and VEE.

Note 7: Guaranteed by design and characterization. Limits are set at ±6 sigma.

Note 8: Measured between outputs of the same parts at the signal crossing points under identical conditions for a same-edge transition.

Note 9: Device jitter added to a jitter-free input signal.

AC ELECTRICAL CHARACTERISTICS

((VCC - VEE) = 2.375V to 3.8V; outputs loaded with 50

Ω ±1% to VCC - 2V; input frequency ≤ 1000MHz; input transition time = 125ps

(20% to 80%); CLK_SEL, FSEL_ = high or low, MR = low; VIHD = VEE + 1.2V to VCC; VILD = VEE to VCC - 0.4V; VIHD - VILD = 0.4V to

1V. Typical values are at (VCC - VEE) = 3.3V, VIHD = VCC - 1V, VILD = VCC - 1.5V.) (Note 7)
