Oscillator family branches out

Vishay has extended its XOSM family of surface-mount oscillators with the release of three new low-voltage devices in miniature packages.

Vishay Intertechnology has extended the XOSM family of surface-mount oscillators with the release of three new low-voltage devices in miniature packages measuring 5.0mm by 3.2mm with a 1.3mm height profile.

Designed to provide space and energy savings in portable computing and telecommunications devices, the new Vishay Dale XOSM oscillators feature an industry-standard footprint size and low input voltage ratings of 1.8V (XOSM-531), 2.5V (XOSM-532), and 3.3V (XOSM-533).

According to a statement, these are the smallest such devices offered by Vishay Dale, and by enhancing the efficiency of clock oscillator circuits, the new low-voltage oscillators also enable the design of better-performing and longer-running end products such as notebook computers, mobile phones, pagers, and PDAs.

The efficiency of the XOSM-531, XOSM-532, and XOSM-533 is said to be enhanced by a tri-state enable/disable function. With low-voltage operation, the devices released today also reduce heat dissipation for improved overall reliability.

The three devices are rated for a frequency range of 1.544MHz to 100.000MHz, and all offer frequency stability options of +/- 25ppm, +/-50ppm, and +/- 100ppm. These lead-free, HCMOS-compatible oscillators are available in tape-and-reel packaging and are compatible with IR re-flow processes.

Samples and production quantities of the new XOSM clock oscillators are available now. Lead-time for production quantities is eight weeks.
