LMX2582: If LMX2582 could be used two-point modulation

Kailyn Chen

Part Number: LMX2582

Hello，

I'd like to confirm with you about this application, could LMX2582 be used 4FSK two-point modulation as below application diagram? The modulation signal is added to the loop filter and the VCO of input reference clock. Is it feasible? I am looking forward your reply.

Best regards

Hi Kailyn,

MOD1 is modulating the VCTCXO, this is not related to LMX2582.

Theoretically speaking, it is possible to modulate the internal VCO, but I am sure there is some tricks behind that need the customer to explore. We do not have experience on this before.
