This appendix is intended to serve as a reference for the receive elastic buffer sizes used in the core and the related maximum frame sizes that can be used without causing a buffer underflow or overflow error.

Throughout this appendix, all analyses are based on 100 ppm clock tolerances on both sides of the elastic buffer (200 ppm total difference). This corresponds to the Ethernet clock tolerance specification.
