NOTES:
2. Gain Error measured as the error in the ratio between the full scale output current and the current through RSET (typically 625µA). Ideally the
ratio should be 32.
3. Parameter guaranteed by design or characterization and not production tested.
4. Spectral measurements made with differential coupled transformer and 100% amplitude.
5. Measured with the clock at 50MSPS and the output frequency at 1MHz, both channels.
6. Measured with the clock at 100MSPS and the output frequency at 40MHz, both channels.
7. See ‘Definition of Specifications’.
8. For operation below 3V, it is recommended that the output current be reduced to 12mA or less to maintain optimum performance. DVDD and
AVDD do not have to be equal.
9. For operation above 125MHz, it is recommended that the power supply be 3.3V or greater. The part is functional with the clock above 125MSPS
and the power supply below 3.3V, but performance is degraded.
10. Measured with the clock at 60MSPS and the output frequency at 10MHz, both channels.
