Figure 3. MAX5858A in 4x Interpolation Mode
This example demonstrates that 4x interpolation with
digital filtering yields significant benefits in reducing sys-
tem complexity, improving dynamic performance and
lowering cost. Data can be written to the MAX5858A at
much lower speeds while achieving image attenuation
greater than 60dB and image separation beyond three
octaves. The main benefit is in analog reconstruction fil-
ter design. Reducing the filter order eases gain/phase
matching while lowering filter cost and saving board
space. Because the data rate is lowered to 71.6MHz,
the setup and hold times are manageable and the clock
signal source is simplified, which results in improved
system reliability and lower cost.
