LMH1983: ferrite beads

Joe Nguyen1

Part Number: LMH1983

Are ferrite beads required on VDD_PLLx and VDD_CLKoutx? EVM has ferrite beads on L6-L11, while datasheet Figure 32 on pg43 does not show any.

Hello Joe,

Ferrite beads are not required for VDD_PLLX or VDD_CLKoutX; however, they are highly recommend to limit crosstalk. Therefore, following the EVM schematic would be my recommendation. Hope this helps!

Good luck,

Andrea
