Fox Electronics has announced its XpressO voltage controlled crystal oscillators (VCXOs) that have low levels of jitter and high performance features so that more information can be transmitted than with traditional programmable oscillators. The XpressO family is available in LVDS and LVPECL versions, and they use noise reducing DSM technology and proprietary low-noise architecture to decrease jitter and phase noise. Their design and application specific integrated circuits (ASICs) allow for accurate performance and increased flexibility. Available package sizes for the 3.3V oscillators are 7.5 mm × 5.0 mm and 5.0 mm × 3.2 mm. They have a frequency range from 1.0 MHz to 1.1 GHz.
