High-Frequency Crystal Oscillators Provide Low-Jitter Performance for Communication Applications
Maxim Integrated Products introduced the DS4-XO series of crystal oscillators that support frequency operation from 75 MHz to 622.08 MHz. These miniature crystal oscillators are available in a 5 mm x 3.2 mm package and provide jitter performance of less than 1 psRMS (12 kHz to 20 MHz) over the -40°C to +85°C extended temperature range. Manufactured using fundamental AT-cut crystal technology with no overtone, the series integrates a low-noise PLL-based oscillator designed in the company's SiGe process. It is suitable for space-constrained designs used in Fibre Channel, Ethernet, 10G Ethernet, SONET/SDH, InfiniBand(R), GPON, BPON, PCI Express(R), and SAS/SATA applications. Prices start at $7.39 for 1000 piece quantities.
