Amplitude Overshoot Reduction
To reduce amplitude overshoot during digital attenua-
tor state change, connect a bandpass filter (parallel
LC type) from ATTEN_OUT (pin 23) to ground. L =
18nH and C = 47pF are recommended for 169MHz
operation (Figure 2). Contact the factory for recom-
mended components for other operating frequencies.
