Hi,

is it correct to leave unused SERDES lanes unconnected?

For example, if we use only 4 lanes for ADC and 4 lanes for DAC.

Regards, Alexander.

Hi Alexander,

Unused ADC and DAC JESD lanes can be left open.

Please note that our latest AFE79xx has same package and size as AFE74xx with lower power per channel, more speed, channels, bandwidth and performance

Regards,

Vijay
