NEL Frequency Controls Introduces Ultra High Frequency Crystal Oscillator

Burlington, WI -- NEL Frequency Controls, Inc. announces the release of its new patent pending Ultra High Frequency Crystal Oscillator available at frequencies up to 2.4 GHz with either Differential Sine, DPECL or LVDS outputs. This frequency control solution is suitable for high speed digital designs where signal integrity is critical. The surface mount package measures 9x14mm.

"Now design engineers have a better solution available in obtaining a high frequency clock reference at a low cost," notes Chuck Ulland, Vice President of Sales and Marketing at NEL Frequency Controls. "Typical approaches of attaining higher frequencies are either using a lower frequency clock with a PLL frequency multiplier or using a SAW oscillator. Both of these approaches have problems: PLL's introduce added jitter, while SAW's have poor stability over temperature performance. NEL's solution offers extremely low jitter and outstanding stability over temperature characteristics."

Typical phase noise performance for 1 GHz is -130dbc @ 10KHz. RMS Random jitter performance is less than 1 psec, from 12 KHz to 10 MHz. Stabilities are from +/-20ppm over a temperature range of 0° to 70° C. The Ultra High Frequency Crystal Oscillator undergoes the rigors of NEL's HALT/ HASS reliability program. It is available in 3.3V and 2.5V versions.
