InSiGa samples industry’s lowest power dissipation 400Gbs MZ driver


Chengdu InSiGa Semiconductor Technologies announced that it has started sampling industry’s lowest power dissipation 400Gbs MZ driver used in Silicon Photonics based 400Gbs applications. 

With the rapid development of 5G, big data, and artificial intelligence, the demand for bandwidth in data centers is increasing day by day. The internal connection rate within datacenters is increasing and there is demand for low power, cheaper modules at high baud rates.

Today, 400Gbs DR4 module that are shipping in high volume predominantly use EML lasers. One of the biggest challenges faced by Silicon Photonics based solutions is higher power dissipation compared to EML based solutions. InSiGa announced availability of industry's lowest power dissipation quad channel MZ driver ( ISG- D5642) for 400Gbs applications to help reduce the power dissipation of Silicon Photonics based modules. The driver is designed to be directly bonded to the modulator eliminating the need of any external caps or inductors. The driver can provide 3.5Vpp differential output and can be digitally controlled using an SPI interface. The driver provides enough gain to be used with all commercially available DSP's. The typical power dissipation of discrete drivers available in market today is about 50% higher than ISG-D5642 under similar output drive conditions. The driver has already been tested with a number of existing Si Photonics based PIC's and is available for sampling now.
