PIN FUNCTION DESCRIPTIONS
DEFINITIONS OF SPECIFICATIONS
Analog Bandwidth
The analog input frequency at which the spectral power of
the fundamental frequency (as determined by the FFT
analysis) is reduced by 3 dB.
Aperture Delay
The delay between the 50% point of the rising edge of the
ENCODE command and the instant at which the analog
input is sampled.

CMOS control pin that enables (SFDR MODE=1) a proprietary circuit that may
improve the spurious free dynamic range (SFDR) performance of the AD9433. It is
useful in applications where the dynamic range of the system is limited by discrete
spurious frequency content caused by non-linearities in the ADC transfer function.
SFDR MODE=0 for normal operation.
Reference input for ADC (2.5V typical)
Internal reference output (2.5V typical); bypass with 0.1uF to Ground.
Analog input – True
Analog input – Complement

Aperture Uncertainty (Jitter)
The sample-to-sample variation in aperture delay.
Differential Analog Input Resistance, Differential Analog
Input Capacitance and Differential Analog Input
Impedance
The real and complex impedances measured at each analog
input port. The resistance is measured statically and the
capacitance and differential input impedances are measured
with a network analyzer.
