Hi,

I have baseband TX and RX signals with BW up to 160MHz, can AFE7225 handle them from ADC/DAC bandwidth point of view?

THanks,

And if it can not support 160MHz, can you please recommend another part which has similar number of AD/DA but capable of 160MHz signal BW?

Thanks,

Tiejun

If you are trying to work with an instantaneous bandwidth of 160 MHz then the AFE7225 *cannot* support that. The AFE7225 operates at 125 MSPS ADC and 250 MSPS DAC which corresponds to max 62.5 MHz and 125 MHz of BW respectively.

Check out AFE7700 integrated transceiver. This is a 4T4R2F integrated transceiver that supports 200 MHz of bandwidth.

If a discrete DAC/ADC option is needed, then there are several options of data converters that are clocked at ~500 MSPS or higher.
