USB BCK Technology in TSMC (22nm, 40nm, 55nm, 65nm, 110nm)
Overview
In USB product series, M31 not only provides customers with a standard USB PHY solution, but also offers a unique BCK(Built-in Clock) function that eliminates the need for an external crystal oscillator. During USB data transfer, the IP performs a background calibration to ensure frequency accuracy. The USB IP with BCK complies with the USB-IF specification and has the same electrical performance as the standard USB IP.
Key Features
- Smallest USB 3.2 Gen1x1 BCK PHY IP worldwide (e.g. IP size @40nm <0.36mm²)
- Fully compliant with Universal Serial Bus USB 3.2 Gen1x1, 2.0, and 1.1 electrical specifications
- Supports clock outputs from the internal BCK module
- Real-time calibrations to ensure frequency accuracy
- Data UI (unit interval) is well-controlled within ±500ppm during data transfer
- Concise and explicit design structure to ease the IP integration
