Figure 15. Hold Mode SFDR vs. Frequency and Input Power at fCLK = 500 MHz

at 10 dBm, FS = Full-Scale Input Level, HFS = Half-Full-Scale Input Level

(Measurement dynamic range for half full-scale and full-scale inputs is

about 68 dB and 74 dB, respectively. Due to measurement noise floor

limitations; measured spurious products tend to limit at these levels.)
