ASSH-25.000MHZ-C-C1 ABRACON

5.0VDC or 3.3VDC 8 PINDIP HCMOS/ TTL LOW EMI SPREAD SPECTRUM CRYSTAL CLOCK OSCILLATORS ASSH 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. Frequency (MHz) APPLICATIONS: ADDITIONAL BENEFITS: Medical Reduce emissions up to 20 dB. Printers Systemic approach to EMI. Scanners Highly cost effective compared to other methods. Modems Eliminate need for individual node suppression. Telecommunications Eliminate need for expensive shielding. Aerospace Reduce component count. Copier Reduce PCB layer count. Automotive Drop-in replacement for 8 pin DIP packages.
