CT20101

Auto-tuning 48MHz Oscillator for USB device without XTAL

CT20101 is an auto-tuning oscillator delivering a precise 48 MHz clock frequency requested by any  USB1.1 or USB2.0 low and full speed USB application. It’s has been designed specifically to minimize the overall system bill-of-material costs and board area by replacing the expensive x-tal device with common and cheap RC external components. Moreover It doesn't require any expensive and time consuming fab or end-of-line trimming.
CT20101 can be easily integrated in any USB device and it can be interfaced with the most diffused USB-PHY and USB controller.
