Note about the use of a Si4464

In Table 3 of the si4464/63/61/60 devices it is told (see page 7, Note 2) that, if possible, the Si4463/61/60 should be used instead of the Si4464.

 

What is the reason for this recommendation?

 

Thank you very much and best regards,

Hi Alberto,

 

The main reason for this recommendation is that the Si4464 is dedicated for +20dBm applications, while if you choose one radio from Si4460/61/63, you can select the one that fits best for your power requirements. For instance, if you need only +10dBm conducted power, you should go with Si4460 to have optimal current consumption for that power. By using Si4464 for +10dBm would generate extra current consumption, since it is not designed for that power range.

 

Also, Si4460/61/63 exist in revC version, while Si4464 has revB radio inside, but that is just an additional note, and not an explanation for the datasheet recommendation.
