Pricing Volatility

Factors influencing pricing volatility in the SerDes market include advanced node wafer costs, SerDes PHY/IP license, high-speed packaging needs, test demands and AI and networking demand volatility. The move from 112G to 224G SerDes will bring added complexity in design and will result in higher engineering, test and manufacturing costs, along with additional costs associated with advanced chipmaking and packaging technology. Additionally, the scarcity of advanced node fab capacity and high-end packaging may result in price volatility in the ASICs, networking chips and optical connectivity parts equipped with SerDes solutions. Consequently, the prices associated with SerDes solutions may range widely according to several factors such as the speed of data transfer, number of lanes, process technology node, IP structure, packaging technology and manufacturing volumes.

Procurement Pressure

The procurement pressure in the SerDes market is growing since artificial intelligence accelerators, networking ASICs, optical transceivers and high-performance computing platforms demand faster and more lanes of connectivity. Increasingly, buyers are assessing SerDes providers not by the price but according to their ability to deliver data rate, efficiency, performance and signal integrity. This situation, along with the relatively small number of vendors that offer 112G/224G SerDes PHYs or high-performance SerDes IP, can lead to qualification dependencies and switching costs; furthermore, the automotive clients have additional requirements on reliability and lifetime of the products. Hence, there is an emphasis on multi-sourcing, IP portability, capacity commitment and total cost of ownership by procurement professionals.

New Technology Adoption

In the SerDes market, new technology adoption is speeding up towards 224G and beyond, being fueled by AI accelerators, hyperscale networking and optical connectivity.

Policies like the U.S. CHIPS and Science Act and EU Chips Act enhance investments in semiconductor ecosystems and national AI and data center policies create more demand for high-bandwidth computing and network infrastructure. These policies provide favorable environment for 112G/224G SerDes, chiplets, optical interconnections and next generation semiconductor packaging, though they are not necessarily SerDes incentives.

Pricing Intelligence

Pricing of SerDes has been driven more by data rates, lane density, process node optimization, protocol support and customization in recent times compared to a fixed pricing formula based on unit prices. Advanced 112G and 224G SerDes have higher development and licensing fees compared to 10-56G due to their complexities involving equalization, clock-data recovery and signal integrity. The price is also determined per lane and per Gbps, especially in cases of AI accelerators, Ethernet switch ASICs, optical DSP and PCIe/CXL interfaces since the addition of more lanes may add to overall connection cost. SerDes used in automotive industry are priced higher due to AEC-Q100 certification, functional safety support and longevity of products whereas customized SerDes PHY IP requires more engineering and integration expenses. Therefore, buyers now consider the SerDes pricing along with power efficiency, bandwidth density, protocol support, certification criteria and integration efforts while selecting vendors.
