Inphi unveils first 800-gigabit PAM-4 signal processing chip
Wednesday, April 8, 2020 at 3:14PM
Inphi has detailed what it claims is the industry’s first digital signal processor (DSP) chip family for 800-gigabit client-side pluggable modules.
Dubbed Spica, the 4-level pulse-amplitude modulation (PAM-4) DSP family is sampling and is in the hands of customers.
The physical-layer company has also announced its third-generation Porrima family of PAM-4 DSPs for 400-gigabit pluggables.
The Porrima DSP with integrated laser driver has being made using a 7nm CMOS process; until now a 16nm CMOS has been used. Fabricating the chip using the more advanced process will reduce the power consumption of 400-gigabit module designs.
