NOTES:
6. Compliance to datasheet limits is assured by one or more methods: production test, characterization and/or design.
7. PSRR is calculated by the equation 20*log10(A/B), where B is the amplitude of a disturber sinusoid on AVDD at the device pins, and A is the amplitude
of the spur in the captured data at the frequency of the disturber sinusoid.
8. AC Specifications apply after internal calibration of the ADC is invoked at the given sample rate and temperature. Refer to
“Power-On Calibration” on9. The DLL Range setting must be changed via SPI for ADC core sample rates below 80MSPS. The JESD204 transmitter can support ADC sample rates
below 100MSPS, as long as the SERDES lane data rate is greater than or equal to 1Gbps.
10. Minimum specification guaranteed when calibrated at +85°C.
Electrical Specifications All specifications apply under the following conditions unless otherwise noted: AVDD = 1.8V, OVDD = 1.8V,
TA = -40°C to +85°C (typical specifications at +25°C), AIN = -2dBFS, fSAMPLE = Maximum Conversion Rate (per speed grade). Boldface limits apply
over the operating temperature range, -40°C to +85°C. (Continued)
