Note 1:
Specifications from T

°
C to +85
°
C are guaranteed by product tests. Specifications from T
A
= +25
°
C to -40
°
C are
guaranteed by design and characterization.
Note 2:
The minimum clock frequency for the MAX5864 is 7.5MHz.
Note 3:
SNR, SINAD, SFDR, HD3, and THD are based on a differential analog input voltage of -0.5dBFS referenced to the amplitude
of the digital outputs. SINAD and THD are calculated using HD2 through HD6.
Note 4:
Guaranteed by design and characterization.
Note 5:
Crosstalk rejection is measured by applying a high-frequency test tone to one channel and a low-frequency tone to the sec-
ond channel. FFTs are performed on each channel. The parameter is specified as the power ratio of the first and second
channel FFT test tone bins.
Note 6:
Amplitude/phase matching is measured by applying the same signal to each channel, and comparing the magnitude and
phase of the fundamental bin on the calculated FFT.
