Linear Technology Selects Ixia's Power Over Ethernet Test Solution

Linear Technology, Corporation (Nasdaq:LLTC), a leading, independent manufacturer of high performance analog integrated circuits, announced today that it selected Ixia (Nasdaq:XXIA), a leading, global provider of high performance IP network testing solutions, to demonstrate and test the full feature capabilities of its Power over Ethernet chipset. Linear Technology employs Ixia's Power over Ethernet test solution to verify and demonstrate conformance of the LTC4259A quad PSE controller to the IEEE 802.3af standard for PoE devices.

"We use Ixia's Power over Ethernet test solution to demonstrate the many functions of our PSE Controller chipset," said Todd Nelson, product marketing manager for Linear Technology's Mixed Signal products. "By utilizing Ixia's PoE test solution, our customers can demonstrate the full capabilities and standard compliance of our solution."

Linear Technology is shipping two quad Power over Ethernet (PoE) controllers that are fully compliant with the IEEE 802.3af specification. These controllers provide autonomous operation for PSE sequencing through all of the required tasks without processor intervention. The precision measurements for detection, classification and current sensing are performed by dedicated internal circuitry with fully specified accuracy.

"Ixia is the first test equipment provider to recognize the industry's need for an integrated, standards-based solution for testing and correlating data and power events in Power over Ethernet-enabled switches and systems," said Dean Lee, product manager for the PoE for Ixia. "We're delighted to help Linear Technology verify their chipset and speed their time- to-market by using our robust PoE solution."

The Ixia PoE test system verifies PD (Powered Device) detection signature ranges, PD classification, maintain power signature for AC or DC disconnect methods (ACMPS and DCMPS), inrush current limiting, short circuit protection, as well as many other capabilities of the Linear Technology devices. The PoE test system is designed for use with Ixia's line of Ethernet network interfaces, which provide data traffic generation and analysis to verify the power sourcing capabilities of the PSE and to verify that data traffic is not impacted by varying power load conditions as defined by the IEEE 802.3af standard.
