Signal Processing & Algorithms Engineer — High-Speed Automotive SerDes SoCs (2–5 Yrs)

Job description

About Texas Instruments Texas Instruments (TI) is a global semiconductor company designing, manufacturing, and selling analog and embedded processing chips — powering everything from industrial automation to automotive safety systems worldwide. About the Team — High Speed Data Interface Product Group The High Speed Data Interface product group focuses on the development of differentiated high-speed SerDes SoCs targeted for automotive and industrial markets. There are two primary focus areas — Ethernet PHY and FPD-Link. Ethernet PHY Group: A large number of applications — like in-vehicle driver alertness monitors, steering, or accelerator control in automotive and robotic applications — require an Ethernet interface. The ubiquity of Ethernet-enabled devices allows customers to simplify connecting large numbers of devices in automotive and robotic environments. Customers expect robust performance in the presence of interference and ESD events, along with processing offload capabilities. The low-cost migration from CAN to Ethernet presents unique challenges requiring interdisciplinary skills with aggressive cost and power targets. FPD-Link Group: The proprietary FPD-Link interface addresses multi-gigabit (up to 20 Gbps) automotive and industrial sensor and display markets. Constant increase in density of electronic sensing and display content is pushing data rate (>20 Gbps) and BER performance requirements higher. Automotive functional safety requirements demand robust performance at these high data rates under challenging environments while maintaining low power consumption. The Broader Mission: As part of this product group, you will be engaged in designing solutions spanning Analog, Digital, and Signal Processing domains to mitigate impairments such as high channel loss, ESD strikes, and narrowband interference. The team implements high-performance equalization circuits (CTLE, FFE, DFE), high-speed converters (DAC, ADC), high-speed digital front-ends, signal processing algorithms, embedded microcontrollers, and high-speed interfaces for camera and display systems. The team has successfully achieved several differentiated innovations through collaborative cross-domain optimization. The entire product lifecycle — from product specification to customer and application support — is owned by the product group in Bangalore, giving each team member tremendous learning opportunity and enhanced scope to influence the global success of the product. We are looking for passionate, creative, and self-driven engineers who challenge traditional techniques and come up with innovative solutions to make a difference.
