100-MHz, HCSL-output XO for PCI Express apps is industry’s first

5.0 x 3.2 x 1.49-mm device saves 55% board space over 7.0 x 5.0-mm solutions

Claimed to be the industry’s first crystal oscillator (XO) to provide the HCSL interface critical for PCI Express applications, the DS4100H saves 55% board space over SAW-based or third-overtone designs. The 100-MHz device provides a jitter performance of less than 1 ps rms (12 kHz to 20 MHz) over -40 to 85C, while delivering much higher frequency stability (±39 ppm versus ±100 ppm or greater) than SAW-based devices.

Additionally, this XO provides ±7-ppm aging over 10 years, whereas SAW-based oscillators typically provide ±1 ppm aging per year. Integrating a LC-PLL circuit that uses a fundamental AT-cut crystal, this XO eliminates the spurious modes of operation typically found in third-overtone designs. The DS4100H is available in a 5.0 x 3.2 x 1.49-mm, 10-pin LCCC surface-mount ceramic package. (From $6.50 ea/1,000—available now.)
