otherwise noted. Typical values are at T
Note 1: Specifications from T
Note 2: The minimum clock frequency for the MAX5863 is 2MHz.
Note 3: SNR, SINAD, SFDR, HD3, and THD are based on a differential analog input voltage of -0.5dBFS referenced to the amplitude
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-
Note 6: Amplitude/phase matching is measured by applying the same signal to each channel, and comparing the magnitude and
