... The entire configuration can be reprogrammed one time allow- ing programmed inventory to be altered or reused. The CY2037 PLL die has been designed for very high resolu- tion. It has a 12 bit feedback counter multiplier and a 10 bit reference counter divider. This enables the synthesis of highly accurate and stable output clock frequencies with zero or low PPM ...
