CM4034ff – 6MHz 3.3V Low Power Oscillator ±1% after trimming. Re-targetable to 1-30MHz
This macro-cell is a low-power, precision, general purpose 3.3V 6MHz ±1% PVT internal oscillator core aimed for clock generation. A 7 bit digital bus allows frequency adjustment against process variations.
It features a self-biased, built-in references.
The core can be easily retargeted to any other frequencies between 1MHz and 30MHz and other CMOS technology that includes poly resistors.
