Industry's First 100MHz, HCSL-Output Crystal Oscillator Designed for PCI Express Applications
Note to Editor:
- The DS4100H is a 100MHz, HCSL-output crystal oscillator packaged in a small, 5mm x 3.2mm package.
- The industry's first crystal oscillator to provide the HCSL interface critical for PCI Express applications, the DS4100H saves 55% board space as compared to 7.0mm x 5.0mm solutions.
- This device employs a high-frequency, low-noise PLL architecture, which is designed using Maxim's proprietary SiGe process.
- The DS4100H XO is ideal for space-constrained, PCI Express applications that require a 100MHz clock with an HCSL output.

SUNNYVALE, CA—March 19, 2008—Maxim Integrated Products (Pink Sheets: MXIM) introduces the DS4100H 100MHz, HCSL-output crystal oscillator (XO) for PCI Express® applications. The industry's first XO to provide a high-speed, current-steering logic (HCSL) output, the DS4100H eliminates the need to translate from CMOS, LVDS, or LVPECL formats to HCSL. Manufactured using fundamental AT-cut crystal technology, it integrates a low-noise, PLL-based oscillator designed using Maxim's proprietary SiGe process. The DS4100H is fifty-five percent smaller than SAW-based or third-overtone designs, making it ideal for space-constrained, PCI Express applications.
Available in a small, 5mm x 3.2mm package, the DS4100H is highly competitive against SAW-based oscillator designs, which are manufactured in a larger, 5mm x 7mm ceramic package and are not offered with an HCSL output. It provides jitter performance of less than 1psRMS (12kHz to 20MHz) over the -40°C to +85°C extended temperature range, while delivering much higher frequency stability (±39ppm versus ±100ppm or greater) than SAW-based devices. Additionally, this XO provides extremely low, ±7ppm aging over 10 years, whereas SAW-based oscillators typically provide ±1ppm aging per year.
The DS4100H also outperforms third-overtone designs, which require additional components in order to translate from other output formats to HCSL. Integrating a robust, 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 space-saving, 5.0mm x 3.2mm x 1.49mm, 10-pin LCCC surface-mount ceramic package. Prices start at $6.50 (1000-up, FOB USA). Samples are available to speed designs.
Maxim Integrated Products, a two billion dollar company, designs and manufactures ICs for analog and mixed-signal applications. The company's broad portfolio of 28 product categories is among the industry's deepest, with over 5400 products.
