USB_BCK

In USB product series, M31 not only provides customers with a standard USB PHY solution, but also offers a unique BCK function. M31’s patented BCK (Built-in-Clock, a.k.a. Crystal-less) technology is an innovative way to save BOM(Bill of Materials) cost by reducing an external crystal for mobile USB devices. In general, this solution has been popularly adopted by those USB devices in applications like flash drive, wireless transmitter, sound card, webcam. 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.

The BCK Series USB PHY still exhibit very good jitter control even if it’s without the external clock sources
