CPRI IQ EUTRA Module

Hi,

The E-UTRA IQ module provided with the current CPRI example design does not support dynamic channel bandwidth.. Are modified  IQ wrappers available which support Dynamic channel bandwidth.. i.e. C_TX_S_n and C_RX_S_n  not constants rather a signal whose value can be changed dynamically..

Hi

 

There are generics to control this.

Refer UTRA-FDD I/Q Module section in PG056 for more detials.

Hi satish,

 

I have already gone through the pg056 datasheet. Those generics values are configurable at synthesis time (It is mentioned in pg056 also). Basically they are constants.

 

In our case, bandwidth information will come from baseband. So we want to make those parameters dynamic (i.e. signal instead of constants). We want to configure those generic values at run time.

 

Thanks and Regards,

Sumala
