MHz operating frequency. This series of micro- crystal oscillator uses small size, 5 mm*3.2mm package, -40 oC to 85 oC extended temperature range provides less than 1 psRMS (12kHz to 20 MHz). DS4-XO series of products based on a frequency not Fengyin AT-cut crystal technology, built-in low noise,PLL-based oscillator, a unique Maxim SiGe process design. DS4-XO products compared to 55% narrowing competition programme for Fibre Channel, Ethernet and 10 G Ethernet, SONET / SDH, InfiniBand, GPON, BPON, PCI Express and SAS / SATA Application of the space compact design is ideal .
DS4-XO series of products using micro-5 mm*3.2mm package, integrated thermal management technology, specifically for high current (65 mA to 75 mA, typical), high frequency (100 MHz or higher), the differential output (LVDS and LVPECL, HCSL) Application Design. Apart from the 100 MHz frequency than all versions are available LVDS and LVPECL output. 100MHz normally used for PCI Express, a (differential) HCSL output types.
As the SAW oscillator based on the commonly used large-size, 5 mm*7mm ceramic package, and is therefore based on SAW oscillator design, this highly competitive series of crystal oscillators. Throughout the extended temperature range, DS4-XO can have considerable phase jitter performance (<1psRMS) on the basis of higher frequency stability (+-40ppm contrast +-100ppm or higher). In addition, DS4-XO series features an ultra-low, +-7ppm of 10 aging, and the SAW oscillator based on the aging of each year is usually to +-1ppm.
Fanyin oscillator design with three different is that DS4-XO-oscillator reliable, frequent use of AT-cut crystal LC-PLL circuit, therefore, completely eliminating the spurious mode, which will not introduce an additional frequency migration. In addition, when necessary, PLL-based design work can be as high as 622.08 MHz or higher operating frequency.
By contrast, three Fengyin design can only provide limited frequency, maximum frequency of about 200 MHz. DS4-XO series of standard crystal oscillator frequency: 77.76 (DS4776), 106.25 (DS4106), 125 (DS4125), 155.52 (DS4155), 156.25 (DS4156), 160 (DS4160), 212.50 (DS4212), 311.04 (DS4311 ), 312.50 (DS4312), 425 (DS4425), and 622.08 MHz (DS4622).
DS4-XO crystal oscillator integrated cooling pad, in the entire extended temperature range of crystal components to ensure safe and efficient work, and suitable for high current (65 mA to 75 mA, typical) applications. The devices use compact space, 5.0 mm*3.2mm*1.49mm, 10-pin, LCCC table paste ceramic package. From$7.39 for the chip (1000, the United States FOB). Samples are now available, can speed up the design process.
