March 23, 2021
Inphi’s 400G DR4 silicon photonics platform includes a silicon photonics integrated circuit (PIC), a flip-chip transimpedance amplifier (TIA), and an analog controller.
Inphi’s 400G DR4 silicon photonics platform includes a silicon photonics integrated circuit (PIC), a flip-chip transimpedance amplifier (TIA), and an analog controller. All are designed to work seamlessly with Inphi’s Porrima™ PAM4 Digital Signal Processor (DSP) to enable faster time to ramp and lower cost per bit. 

Judge’s comment: “A full set of analog and DSP chips with excellent performance to implement latest generation pluggable modules. Availability compatible with high-volume, low-cost manufacturing, i.e., can get components at full wafer scale, which is quite innovative for the industry."
