<p>Contact WRT sales by email at <a href="mailto:sales@wildrivertech.com">sales@wildrivertech.com</a> or by phone at 1-800-604-0858 to arrange a web-based meeting to discuss your requirements with the WRT ESI Team:</p>

<li>Please be prepared to discuss the high-level objectives, rough schedule, what level of future-proofing is required, and ancillary requirements (cost, production volume, mechanical or thermal requirements, etc.).</li>
<li>We also like to identify the level of signal integrity challenge, operating bandwidth, rise/fall times, signal integrity margins, etc. If you do not know this, WRT will help you since these metrics are not always straightforward.</li>
