XU and XL families of crystal oscillators

Integrated Device Technology has introduced its XU and XL families of crystal oscillators that have 300fs and 750fs typical RMS phase jitter, respectively, from 12kHz to 20MHz. The crystal oscillators are designed for networking, communications, data I/O and server applications.

The XU family delivers varying throughput speeds to match the requirements of individual designs. These devices provide LVPECL, LVDS, HCSL and HCMOS outputs with operating voltages of 3.3V, 2.5V and 1.8V. Available in 7mm×5mm and 5mm×3.2mm packages, XU oscillators furnish frequency stabilities as low as ±20ppm and operate over a temperature range of -40°C to 85°C.

The XL series of oscillators comes in LVPECL, LVDS and HCMOS versions with operating voltages of 3.3V and 2.5V.

They also offer frequency stabilities as low as ±20ppm and an operating temperature range of -40°C to 85°C. The XL devices are available in 7mm×5mm, 5mm×3.2mm and 3.2mm×2.5mm packages.
