CT20101 is an auto calibrating oscillator delivering a precise 48 MHz clock frequency required by any USB1.1 or USB2.0 low and full speed USB application.
It has been designed specifically to minimize the overall system bill-of-material costs and board area by not employing the expensive x-tal device. Fab trimming is required to tune a fully internal time reference (100KHz clock) and requires 4 bits.
CT20101 can be easily integrated in any USB device and it can be interfaced with the most diffused USB-PHYs and USB controllers.
