AC ELECTRICAL CHARACTERISTICS—VGA MODE
(Figure 7, V
TMODE = 0, PD = 0, CW_VG = 1, CW_M1 = 0, CW_M2 = 0, VG_CLAMP_MODE = 1, f
each of the VGA differential outputs is 60pF, differential capacitance across the VGA outputs is 10pF, R
pulled up to +11V through four separate ±0.1% 115Ω resistors, differential mixer inputs are driven from a low-impedance source.
Typical values are at V
