View ArticleRe: AD9364 charge pump current and bleed current
Current in 0x046 is not CP bleed current, it is CP current. The provided device drivers configure the AD9361/4 for a given set of parameters. Charge pump configuration is part of this configuration.
View ArticleRe: AD9364 charge pump current and bleed current
When you say "charge pump configuration", does this also include any configuration for bleed current? Is BBPLL bleed current customization something that ADI doesn't want customers to change?
