Today’s high speed serial applications are driving increasing capacity and performance. To meet these demands designers are going to higher clock speeds and greater power densities. Both of the needs are supported by the ultra-low phase jitter OA-U series. The OA-U series may be specified at an any frequency from 100 MHz up to 175 MHz and is able to operate at temperatures up to +125°C. With typical phase jitter of 50 fs @ 156.25 MHz, the OA-U series is the ideal clock solution for high-speed serial applications such as network switching, optical communications and Storage Area Networks (SAN). The miniature 3.2 x 2.5 mm SMD package also enables more compact system designs and lower total cost.
Leveraging Taitien’s vertical integration production of quartz wafers and low phase noise oscillation circuit design technology, the newly launched OA-U series is available from 100 MHz to 175MHz with the phase jitter = 100fs rms, maximum. There are 3 logic outputs: LVPECL, LVDS and CML and the supply voltages are 2.5 V and 3.3 V. The frequency stability maybe specified as tight as ±25 ppm over -40°C to +85°C or ±50 ppm over -40°C to +125°C.
