DS90UB954-Q1: PoC Bead 1500k-ohm+1500k-ohm or 47-ohm+330-ohm

Ting Ye

Part Number: DS90UB954-Q1

Hello Team,

DS90UB954-Q1 datasheet suggested beads (1500k-ohm+1500k-ohm) at PoC are different than 954 EVM (47-ohm+330-ohm) suggested.

May I know which one is suggested?

Thank you.

Ting,

The FB is used to block the high speed forward signals at ~2Gbps, it is better if impedance is higher. so 1500ohms in d/s is better than the design in EVM's board. You can use d/s's suggestion for your customer, thanks.

best regards,

Steven
