At present, there are three chips on the market based on TSMC's 5nm process (N5), which are Kirin 9000 5g SOC in Huawei mate 40 pro, A14 SOC in Apple iPhone 12 series intelligent machine, and M1 SOC used in Apple silicon Mac.Now there's a new addition to the list, Marvell's 112G SerDes connection chip.
AnandTech report that Marvell just released 112 G SerDes solutions based on digital signal processors.
Modern network infrastructure relies on high-speed SerDes connections and can work at various rates and Protocols (such as Ethernet, fiber, storage and connectivity).
Previous products have supported up to 56g of connectivity, but the latest IP supports doubling it. Although Marvell was the first manufacturer to provide 1125nm, it was not the first manufacturer to connect.
Compared with high-speed and high reliability, it not only meets the requirements of high-speed and high reliability, but also meets the requirements of various standards.
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 and insertion loss greater than 40dB.
Generally, data supports NRZ modulation based on a series of 0 or 1 operation bits, but Marvell enables 2-bit operation (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.
Marvell said it has contacted ASIC custom customers in multiple markets to deploy 112G SerDes solutions. In addition, Marvell will support a complete set of solutions based on 5nm PHY, switches, DPUs, custom processors, controllers, accelerators and other products.
