LMX2571: Two fanout outputs with same signal outputs

F.N

Part Number: LMX2571

Hi team,

My customer wants to use LMX2571 as two fanout outputs.

So, the customer asks how to set the T/R switch to be configured as a fanout buffer to out
the same signal at both RFoutTx and RFoutRx ports at the same time.

Please let me know the related register settings and the TrCtl pin setting.

Best regards,
Fumio Nakano

Hi Nakano-san,

If both output frequencies are identical, you only need one register set (either F1 or F2 register set) but need to enable both TX and RX port.

For example,

BTW, are you working with Masaharu-san on this?
