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).
