A company’s high-performance, spread-spectrum clock oscillators and EMI suppression adapters can reduce electromagnetic emissions and associated harmonics up to 20 dB. Applications include aerospace, telecommunications, medical capital equipment, and consumer electronics. Advanced spread-spectrum modulators, which have a standard TTL or CMOS-compatible output, meet clock requirements of all major CISC, RISC, and DSP processors. EMC oscillators serve as replacements for crystal oscillators and are plug compatible to standard 14-pin, 8-pin, and surface-mount packages. All EMC oscillators are available in selectable output frequencies that range from 4 to 128 MHz. Drop-in assemblies for back-end integration eliminate costly redesign and production delays, and EMC low-noise oscillator products can reduce dB up to 20%, enabling products to satisfy EMI standards.
