• Manufacturer Part Number: MAX2066
• Description: Serial/Parallel-Controlled Digital VGA
• Manufacturer: Maxim Integrated Products

50MHz to 1000MHz High-Linearity,
Serial/Parallel-Controlled Digital VGA
Table 6. Typical Application Circuit Component Values (HC Mode)
Table 7. Typical Application Circuit Component Values (LC Mode)
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.
