  7. 4Revision History

3.14 Crystal connected to osc0 needs to have 50 ppm or better long term accuracy

The crystal connected to osc0 needs to have 50ppm or better long term accuracy since it generates clocks used for Ethernet interfaces. The current crystal has 30ppm accuracy and 50ppm temperature variation for a combined tolerance of 80ppm. It also has aging of 2ppm per year.
