Ethernet PHY Application Development Kits

Thursday, February 15, 2018

 Mission Viejo, CA (January 16, 2018) – Holt Integrated Circuits today announced the release of two new 10Base-T/100Base-TX Ethernet PHY application development kits. The kits feature Holt’s recently announced Ethernet PHY transceiver family, HI-5200/HI-5201, designed specifically for extended temperature military and aerospace applications. 

The ADK-5200 application development kit provides access to all PHY configuration pins and includes a readily accessible MII or RMII interface using HI-5200, which can be easily connected to an external MAC via the on-board connector. Other features include a RJ-45 Jack for “Fast Ethernet” cable connection, programmable LEDs for reporting link status and activity, and a manual reset button for quick reboot after reconfiguration of strapping pins. The ADK-5201 application development kit is identical but features HI-5201, a 10Base-T/100Base-TX PHY which has an enhanced RMII interface, generating a 50 MHz RMII reference clock output for the MAC. 

“These Ethernet PHY application development kits provide our customers with a convenient platform to evaluate the features of Holt’s extended temperature Ethernet PHY family and can be used as a starting point for new designs or a test and evaluation platform,” said Anthony Murray, Director of Marketing Communications at Holt.

The HI-5200/5201 PHY family is capable of operating from a single 3.3V power supply over the temperature ranges of -40oC to 105oC and -55oC to 125oC, with optional burn-in available. These extended temperature Ethernet PHY devices eliminate the need to up-screen commercially available products and give customers the assurance of product longevity from a well-established military and aerospace supplier.
