We are pleased to announce that in May 2025, the error-correcting line code 4b/10b, developed by the Yamasaki Laboratory, has been officially published as an international standard IEC 63455:2025.
4b/10b is a table-based line code that converts 4-bit data into 10-bit symbols. This code achieves 1-bit error correction and 2-bit error detection solely through table lookup, while also providing DC balance and clock embedding performance superior to 8b/10b. This enables low-latency, stable communication even in noisy environments, making it a suitable code for real-time communication.
