(9) Clamp Overshoot Width is the duration of overshoot in a 100% overdrive condition.
(10) Linearity Guardband is defined for an output sinusoid (f = 75 MHz, V
OD
= 2 V
PP
). It is the difference between the V
CLAMP
level and the
peak output voltage where the SFDR is decreased by 3 dB.
(11) Negative current implies current flowing out of the device.
