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