The junction temperature (TJ) range of −10°C to +120°C translates to an ambient temperature (TA) range of −40°C to +85°C.

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

Default mode. No DDCs used.

Can be controlled by the SPI.

AC SPECIFICATIONS

AVDD1 = 0.975 V, AVDD1_SR = 0.975 V, AVDD2 = 1.9 V, AVDD3 = 2.5 V, DVDD = 0.975 V, DRVDD1 = 0.975 V, DRVDD2 = 1.9 V,

SPIVDD = 1.9 V, sampling rate = 2.0 GHz/2.56 GHz, clock divider = 2, 1.7 V p-p full-scale differential input, input amplitude (AIN) =

−2.0 dBFS, default SPI settings, −10°C ≤ TJ ≤ +120°C,1 unless otherwise noted. Typical specifications represent performance at TJ = 70°C

(TA = 25°C).
