Typical Operating Characteristics (continued)
(
Typical Application Circuit, VREF = 2.475V to 2.525V, VCC1 = 3.13V to 3.47V, VCC2 = 4.5V to 5.25V, TA = 0°C to +70°C, VGND = 0V,
NP = 0, PD = 0, CLP = 0, D43/D42/D41/D40 = 1/0/1/0 (RIN = 200Ω, LNA gain = 18.5dB), D45/D44 = 1/1 (fC = 18MHz), fRF = fLO/16
= 5MHz, capacitance to GND at each of the VGA differential outputs is 25pF, differential capacitance across VGA outputs is 15pF,
RL = 1kΩ differential, RS = 200Ω, CI_, CQ_ pulled up to 11V through four separate 0.1% 162Ω resistors, the rise/fall time of the LVDS
clock driving the LO_ is required to be 0.5ns, reference noise less than 10nV/
√Hz from 1kHz to 20MHz, DOUT loaded with 10MΩ
and 60pF. Typical values are at VCC1 = 3.3V, VCC2 = 5V, TA = +25°C, unless otherwise noted.)
