Note 2:

Test-channel input grounded through a 50

Ω resistor. Adjacent channel driven to a 2Vp-p output with a 10MHz sine wave

(Figure 9).

Note 3:

Same as Note 2, except all channels but the test channel are driven to a 2Vp-p output with a 10MHz sine wave (Figure 9).

Note 4:

Test-channel input connected to a 2Vp-p sine wave at 10MHz. The test channel’s output is measured with the outputs

disabled (Figure 9).

Note 5:

Input test signal is a 3.58MHz sine wave of 40IRE amplitude, superimposed on a 0IRE to 100IRE linear ramp (Figure 10).

Note 6:

Guaranteed by design.

Note 7:

VINA = +1V, VINB = -1V, delay from CS to 10% of VOUT.

Note 8:

VINA = +1V, VINB = -1V, delay from CS to 10% of VOUT.

Note 9:

Delay from

EN to 90% of VOUT.

Note 10: Delay from

EN to 10% of VOUT.
