ACSD

5.0VDC or 3.3VDC • 8 PIN DIP • HCMOS/ TTL LOW EMI SPREAD SPECTRUM CRYSTAL CLOCK OSCILLATORS ACSD and ACSDL FEATURES: • Integrated Spread Spectrum technology • Standard TTL or HCMOS output. • Meets clock jitter requirements for all major CISC, RISC and DSP processors • Wide frequency range from 4 MHz to 128 MHz. CENTER 480.00 MHz MKR 1.05 MHz -15.66 dB 15.7dB EMI reduction 5th Harmonic of 96 MHz APPLICATIONS: • • • • • • • • Medical Printers Scanners Modems Telecommunications Aerospace Copier Automotive ADDITIONAL BENEFITS: • • • • • • • • Reduce emissions up to 20 dB. Systemic approach to EMI. Highly cost effective compared to other methods. Eliminate need for individual node suppression. Eliminate need for expensive shielding. Reduce component count. Reduce PCB layer count. Drop- in replacement for 8 pin DIP packages.
