Precision Crystal Oscillators for Highly Accurate Timing Applications
- click to enlarge
Maxim offers a complete line of TCXO, VCXO, XO, and RTC products for precision timing applications. These devices support high-speed data communications including SONET, Ethernet, SAS/SATA, PCI, PCI Express®, Fibre Channel, and InfiniBandSM applications.
High-precision TCXO devices, including the DS4026, provide better than ±1ppm accuracy with < ±4.6ppm aging over 15 years. High-frequency XO products, such as the DS4-XO product series, are provided in miniature 5mm x 3.2mm ceramic packages and cover frequencies from 77.76MHz to 622.08MHz. Accurate RTC solutions include the award-winning DS3231 accurate RTC, which can provide < ±2min/yr accuracy for real-time clocks. The DS4077 VCXO provides excellent phase-noise performance for applications such as base stations, routers, and HD-SDI video systems.
