10-Gigabit Endpoint core expands CAST's TSN portfolio for automotive, industrial,
                  aerospace, and critical infrastructure applications 


Woodcliff Lake, NJ — March 11, 2026 — CAST, a leading provider of semiconductor
intellectual property cores, today announced the TSN-EP-10G TimeSensitive Networking (TSN)
Endpoint IP core, extending its established TSN portfolio to support 10-Gigabit Ethernet (10
Gbps) for automotive, industrial automation, aerospace, rail, marine, and defense markets. 


CAST's new TSN-EP-10G targets high-bandwidth, time-synchronized Ethernet architectures,
delivering a tenfold increase in data rate over its 1G predecessor while preserving the
deterministic behavior required for real-time Ethernet systems.  


      “High-speed, real-time Ethernet networks are increasingly serving as the communications
      backbone for new systems, and these require the precise time synchronization that TSN
      enables,” explained Alexander Mozgovenko, CAST TSN product manager. “The determinism
      enabled by the TSN IP cores we offer—now at the 10 Gbps performance level—helps make
      it straightforward for developers to produce advanced systems that require highly reliable
      communication.” 


Standard, non-TSN Ethernet is inherently asynchronous, offering no scheduling or predictability
of packet delivery timing. TSN augments Ethernet with precise time synchronization and traffic
management to enable deterministic packet delivery, especially important for mission-critical
and life-safety applications. 


Integrated TSN Feature Set 

The TSN-EP-10G IP core integrates a low-latency Ethernet MAC with hardware support for key
IEEE TSN functions, including IEEE 802.1AS-2020 gPTP Time Synchronization,
IEEE 802.1Qav Credit-Based Shaper (CBS), and IEEE 802.1Qbv Time-Aware Scheduling (TAS). 


Additional TSN capabilities are supported through optional modules and software, enabling
features such as: 

      •  802.1CB Frame Replication and Elimination for Reliability (FRER),
      •  802.1Qci Per-Stream Filtering and Policing (PSFP)  
      •  802.1Qcc Stream Reservation Protocol (SRP), and  
      •  802.1Qca Path Control and Reservation (PCR). 


Software support for both FreeRTOS™ and Linux® (including gPTP stack, drivers, CLI, and
integration) helps speed implementation of advanced real-time Ethernet designs. 


Overall, the new 10G TSN endpoint core enables very high data rates yet ensures a stable
network time base, achieving data synchronization accuracies under 10 nanoseconds.  


TSN Portfolio with Flexible Integration 

CAST offers a competitive TSN IP portfolio that also includes a 1G TSN Endpoint, a two-port
Switched Endpoint, and a three- to twenty-four-port Switch. Sourced from Fraunhofer
IPMS, these cores help customers integrate deterministic Ethernet quickly, while maintaining
control over implementation, performance, and power optimization. Dozens of customers
worldwide are using the TSN IP from CAST, reflecting growing adoption as Ethernet becomes
the backbone of real-time, safetycritical systems. 


The TSN-EP-10G interfaces with PHY devices via XGMII. It is available as synthesizable RTL
for ASIC and FPGA designs and as netlists for most FPGA families. Reference designs,
testbenches, and software stacks are available; contact CAST with specific project
requirements.
