| 5.0VDC or 3.3VDC * 14 PIN DIP * HCMOS/ TTL LOW EMI SPREAD SPECTRUM CRYSTAL CLOCK OSCILLATORS ASSO FEATURES: * Integrated Spread Spectrum technology * Standard TTL or HCMOS output. * Meets jitter requirements for all major CISC, RISC and DSP processors * Frequency Range of 15 to 120 MHz @ 5.0 VDC. * Frequency Range of 15 to 90 MHz @ 3.3 VDC. Amplitude (dB) Frequency (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 14 pin DIP packages.
