Infineon's oscillators portfolio

CY294X is a family of high-performance, PLL-based programmable crystal oscillators and clock synthesizers. The low-noise, programmable PLL technology allows CY294X to produce any frequency between 15 MHz and 2,100 MHz, while achieving a typical phase jitter of 0.11 ps. The device supports popular output types such as LVPECL, LVDS, HCSL, LVCMOS, and CML. Additional features include frequency margining and VCXO functionality. These devices are available in QFN and LCC packages. CY294xx devices generate one differential (or one single-ended) output up to 2.1 GHz with RMS jitter as low as 110 fs. They are factory- or field-programmable; the configuration stored in the volatile memory can be controlled over the I2C interface.
