Scope probe measures high frequencies

Scope probe measures high frequencies

measuring clocks and critical signals accurately is often inconvenient and hard to do accurately with normal 10? probes, this article describes 100? probe that is easy to make and use, has a high bandwidth, and has a small (less than 1 pF) input capacitan

Selecting passive components for PLLs

Selecting passive components for PLLs

PLLs in SERDES circuits typically require external resistors and capacitors. Other PLLs, such as cleanup circuits with high-Q VCXOs, also use external components. Theory and practical experimentation combine to enable you to optimize these component value
