Xilinx SERDES technology, senior product marketing manager Panch Chandrasekaran said: "Linear Technology Corporation worked closely with Xilinx, developed specifically for applications requiring low noise performance of new products. We have these new DC / DC uModule tests carried out showed that they can provide power for the RocketIO linear regulators considerable (in some cases even better) the noise performance and jitter tolerance. "

Linear Technology DC / DC uModule Afshin Odabaee product marketing manager, said: "Our mutual customers asked us to drive the development of multi-gigabit transceiver power, high efficiency and low noise DC / DC solutions , because the linear regulator in a number of customer applications too much heat dissipation. "

This four DC / DC uModule is LTM8023 (2A), LTM4604 (4A), LTM4606 (6A) and LTM4616 (dual output, 8A). This series provides 2A to 8A of output current, the 2.375V to 36V input range. Their LGA (land grid array) package the size of its power and functions as may be, ranging from 9mm × 11.25mm × 2.8mm to 15mm × 15mm × 2.8mm.

In short, the test device used eight different SERDES channels - of which two channels for measuring jitter tolerance, while the other six channels are in the loopback mode. Test equipment used, including: HP461A and Agilent DSO 54855 (for TX output jitter measurement), BERT Scope-S (for RX jitter tolerance measurements).
