Upgrading a design based on Si4777-A20 to Si468x-A10

I want to upgrade an existing Si4777-A20 based AM / FM design to include DAB+ and consider using a Si4685-A10.

 

For some features the following is required:

a) I/Q baseband data output (for external DRM and DRM+ decoding)

b) FM MPX signal output (for external VICS and DARC decoding)

 

 

Si4777-A20 offered I/Q baseband data output and FM MPX output:

Si4777-A20

Does Si4685-A10 also offer these or is there another member of the Si468x series which offers these outputs?

Si4685-A10

 

I'd like to avoid a solution with 2 receiver chips (Si4777 for AM / FM and Si468x for DAB).

 

Best regards,

Andi

Hi Andi,

 

No,  we dont support I/Q baseband output or MPX out on Si468x product family.

 

Can you kindly let me know your target application and the MP date?

 

What co-processor are you using for DRM/DRM+ decoding?

 

Regards

Abhijit

Dear Abhijit,

 

The target application will be a high-performance radio receiver, targeted to Europe, with FM, AM, DAB+ and DRM(+). Application will be non-automotive.

 

Development and first prototype / sample assembly is planned for 2016.

MP date is expected to be in 2017.

 

Best regards,

Andi
