AC ELECTRICAL CHARACTERISTICS—CW MIXER MODE
( Typical Application Circuit , Figure 7. V
CW_FILTER = 1, TEST_MODE = 0, PD = 0, CW_VG = 0, CW_M1 = 0, CW_M2 = 0, VG_CLAMP_MODE = 1, f
capacitance to GND at each of the VGA differential outputs is 60pF, differential capacitance across the VGA outputs is 10pF, R
1kΩ, CW mixer outputs 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
