6 Summary

Based on jitter and bit error tests performed, the following are key observations.

  • CDC6C passes the IEEE 100Mbps requirements of IEEE 802.3 and IOL’s (InterOperability Laboratory) interoperability test bed
  • BAW oscillator helps reduce output jitter of both channels A and B which reduces the noise of Ethernet PHY output.
  • BAW oscillator help improve PHY performance and in turn improves bit error rate of the Ethernet PHY
