AMC1303M2520: p2p Alternatives recommendation

Hi team,

My customer need p2p replacement for AMC1303M2520DWV due to shortage. I recommended AMC1303x series and AMC1306M25. But customer feedback that the proposals can’t be drop-in replacement for our machines.

Reasons: 

• AMC1306M series without internal clock
• AMC1303M05 with 0.002ohm may degrade the SNR

I'd like to require your suggestion on it. Is there any better choice for this replacement?

Thanks!
