    Components: Improved-Stability VCXO Oscillators Cover Industrial Temperature Range

    Nov. 24, 2003
    Housed in a surface-mount 9- by 14-mm package, the VPLD6 series of voltage-controlled crystal oscillators (VCXOs) features various frequency stabilities ranging from 100 ppm down to 20 ppm. With those frequency stabilities, the oscillators still...

    Housed in a surface-mount 9- by 14-mm package, the VPLD6 series of voltage-controlled crystal oscillators (VCXOs) features various frequency stabilities ranging from 100 ppm down to 20 ppm. With those frequency stabilities, the oscillators still operate over the industrial-temperature range of −40°C to 85°C. Available in frequencies from 16.384 to 200 MHz, they meet Sonet/SDH and phase-locked-loop (PLL) low-jitter and tight-temperature-stability requirements. The VCXOs feature differential PECL outputs. Total stability is guaranteed for all types of frequency variabilities, including 15-year aging. Prices start at $8.95 each in quantities of 5000. Lead time is within four to eight weeks.
