Modern network infrastructure relies on high-speed SerDes connections and can work at various rates and Protocols (such as Ethernet, fiber, storage and connectivity). < / P > < p > previous products have supported up to 56g of connectivity, but the latest IP supports doubling it. Although Marvell is not the first manufacturer to offer a 112G connection solution, it is the first company to adopt a 5nm process. Compared with competitive products, it not only meets various standards, but also has lower energy consumption and error rate, which is of great practical significance for high-speed and high reliability infrastructure applications. < p > < p > Marvell claims that its new scheme can significantly reduce the energy consumption per bit transmission, which is 25% lower than the competitive products based on TSMC’s 7 nm process (N7), and has strict power / thermal constraints, as well as an insertion loss of more than 40dB. < / P > < p > data usually supports NRZ modulation based on a series of 0 or 1 operating bits, but Marvell enables 2-bit operations (00, 01, 10 or 11), also known as pam4 pulse amplitude modulation. This can easily double the bandwidth, but it does require some extra circuits. < / P > < p > as a future oriented technology, some people may have known that NVIDIA RTX 3090 uses pam4 signal modulation based on 7Nm technology, which can provide more than 1000 GB / s bandwidth for Meguiar gddr6x flash memory chip. If necessary, it can also be operated in NRZ mode to reduce power consumption. Marvell said that it has contacted ASIC custom customers in multiple markets to deploy 112G SerDes solutions. In addition, Marvell will support a set of solutions based on 5nm PHY, switch, DPU, custom processor, controller, accelerator and other products.
