PRODUCTION DATA
The front end sampling glitch filter is designed to optimize the SNR and HD3 performance of the ADC. The filter performance is dependent on input frequency and therefore the following filter designs are recommended for different input frequency ranges as shown in Figure 8-4 and Figure 8-5 (assuming 50 Ω source impedance).
Figure 8-4 Sampling
glitch filter for input frequencies from DC to 30 MHz
Figure 8-5 Sampling
glitch filter for input frequencies from 30 to 70 MHz
