Hi

Just wont to approve the Sharc cores max clock rate.

it used to be 450Mhz and now I see in ADI site, it was update to 500Mhz.

Is it correct? Are there no heating problems?

Thanks in advance

Alon.

Hi Alon,

Please refer the datasheet of ADSP-SC5xx.
www.analog.com/.../ADSP-SC582_583_584_587_589_ADSP-21583_584_587.pdf

Yes, it is support up to 500 MHz per SHARC+ core. Please let us know which part number are you using? It will also dependant upon the processor part which you having.

Hi Lalitha,

Are there any risk if we run 500MHz on ADSP-21584BBCZ-4A at 0C to 70C? Thanks.

Hi,

As per the datasheet, ADSP-21584BBCZ-4A supports maximum Processor Instruction Rate of 450MHz at –40°C to +85°C . We cannot guarantee the proper operation of the devices if the specification not followed. So, we would suggest you to follow the specifications as mentioned in datasheet.
