START-UP SEQUENCE
To ensure proper start up, follow one of the following steps when powering up the SLK2511B.
1. Keep ENABLE (pin 44) low until power supplies and reference clock have become stable.
2. Drive ENABLE (pin 44) low for at least 30 ns after power supplies and reference clock have become
stable.
The following step is recommended with either of the above two sequences.
3. Drive RESET low for at least 10 ns after link has become stable to center the TXFIFO.
