100-MHz/HCSL-Output Crystal Oscillator Rides The PCI Express
Heralded as the industry's first crystal oscillator for PCI Express applications with a high-speed, current-steering logic (HCSL) output, the DS4100H eliminates the need to translate from CMOS, LVDS, or LVPECL formats to HCSL. Exploiting fundamental
Heralded as the industry's first crystal oscillator for PCI Express applications with a high-speed, current-steering logic (HCSL) output, the DS4100H eliminates the need to translate from CMOS, LVDS, or LVPECL formats to HCSL. Exploiting fundamental AT-cut crystal technology, it integrates a PLL-based oscillator employing the company's proprietary SiGe process. According to the company, the device is 55% smaller than SAW-based or third-overtone designs in larger, 5 mm x 7 mm ceramic packages without an HCSL output. Other features include a jitter performance of less than 1 ps rms from 12 kHz to 20 MHz, operating temperature range from -40°C to +85°C, and ±7 ppm aging over 10 years. Available in a 10-pin, 5 mm x 3.2 mm x 1.49 mm surface-mount LCCC package, price starts at $6.50 each/1,000. MAXIM INTEGRATED PRODUCTS, Sunnyvale, CA. (800) 998-8800.
