Inquiries about Sample rate converter of ADSP-21488

Hi All,

I have a question about ADSP-21488.

There are the following two product numbers for this model number.

・ ADSP-21488KSWZ-4B

・ ADSP-21488KSWZ-4B1

According to DataSheet (), these differences are probably due to the Sample Rate Converter.

Is there a hardware difference such as a change in the internal clock?

Best Regards,

Takahiro
