LMX2581E: Performance difference between LMX2581 and LMX2581E

Part Number:LMX2581E

Hi Team,

Could you please help us explain the difference between LMX2581 and LMX2581E ?

1). What is the background of LMX2581E development ?

2). Are there any performance difference other than VCO frequency range between LMX2581 and LMX2581E ?

Best Regards,

Kawai
