¹All lanes running. Power dissipation on DRVDD changes with lane rate and number of lanes used.

²Default mode. No DDCs used. L = 4, M = 2, F = 1.

³N/A means not applicable. At the maximum sample rate, it is not applicable to use L = 2 mode on the JESD204B output interface because this exceeds the maximum

lane rate of 12.5 Gbps. L = 2 mode is supported when the equation ((M × N΄ × (10/8) × f_OUT)/L) results in a line rate that is ≤12.5 Gbps. f_OUTis the output sample rate and

is denoted by f_S/DCM, where DCM is the decimation ratio.

⁴Can be controlled by the SPI.

AC SPECIFICATIONS

AVDD1 = 1.25 V, AVDD2 = 2.5 V, AVDD3 = 3.3 V, AVDD1_SR = 1.25 V, DVDD = 1.25 V, DRVDD = 1.25 V, SPIVDD = 1.8 V, specified

maximum sampling rate for each speed grade, A_IN= −1.0 dBFS, clock divider = 2, default SPI settings, T_A= 25°C, unless otherwise noted.
