Fox Electronics, a leading global supplier of frequency control solutions and an IDT company, now offers an LVDS version, in addition to the recently released LVPECL version of its next generation ultra precision oscillator technology, XpressO-ULTRA.  Designed to meet today’s intense bandwidth requirements that need ultra precision timing technology, XpressO-ULTRA provides exceptionally clean and stable clocking to ensure better performance and lower bit rate errors.

The new ultra precision oscillators, which come in 2.5 V or 3.3 V, with its Ultra Low Jitter as low as 100 fs over the 1.875MHz-20MHz bandwidth and 250fs over the 12kHz to 20Mhz bandwidth, can be used on a number of modern electronics that employ extremely demanding data speeds of 40G to 100G Ethernet, 16G-32G Fibre Channel, 100G-400G Optical Transport Networks and others.

Operating temperature from -20~+70C to -40°C ~ +85°C with stabilities as tight as ±20 ppm. The new ultra precision oscillators come in an industry standard 5 x 3.2 mm package and pin-out. A tri-state enable/disable feature allows for testing and performance verification. The RoHS-compliant units offer a gold over nickel termination finish.

Fox’s LVDS XpressO-ULTRA oscillators employ the cost and time saving design process as the company’s groundbreaking XpressO technology.  A new proprietary ASIC family, developed by Fox, with a 4th order Delta Sigma Modulator (DSM) that significantly reduces noise to levels comparable with traditional bulk quartz and SAW oscillators.  The ASIC family enables the configuration of output type, input voltages and frequency within the oscillator.

Delivered in less than two weeks at an exceptionally low cost, XpressO-ULTRA oscillators offer low noise, a wide frequency range and excellent performance for high bandwidth data applications.

Each XpressO-ULTRA oscillator is outfitted with a unique serial ID to track every aspect of the manufacturing process for exceptional quality assurance.
