Micrel Rolls Out Two LVPECL and LVDS Clock Synthesizer Timing System-On-a-Chip IC Solutions
Synthesizers Ideal Clock Source for Interface Cards Requiring Legacy Compatibility or Interface Card Timing Options
SAN JOSE, Calif., Oct. 12, 2005 -- Micrel, Inc. (Nasdaq: MCRL - News), an industry leader in analog, high bandwidth communications and Ethernet IC solutions, today released two precision, low-jitter clock synthesizers that provide an extremely high level of integration for system timing generation. The SY89537L and SY89538L include a PLL that accepts a crystal or reference input, multiple clock dividers, and four LVPECL outputs and one LVDS output bank of three that are all externally programmed for output frequencies between 29MHz and 756MHz. Both devices are fully released to production and available in volume quantities. Pricing starts at $9.94 for 1K quantity.
"Micrel's new clock synthesizers provide a new level of integration for large, differential LVPECL and LVDS clock generation and distribution applications," noted Thomas S. Wong, vice president of Micrel's high bandwidth product group. "Using these solutions, networking timing and routing engine cards will see a tremendous cost savings as well as a significant savings in board space and design time when compared to the discrete logic alternatives currently on the market."
The SY89537L and SY89538L both feature a PLL front end that synthesizes a clock from a crystal or clock reference input. Output frequency is programmed between 29MHz and 756MHz with a 6-bit parallel control bus. In addition, each LVPECL output and LVDS output bank can switch between two clock frequencies, making it an ideal clock source for interface cards that require legacy compatibility or interface card timing options.
The SY89537L and SY89538L are both 3.3V +/-10 percent compatible, and are guaranteed over the full industrial temperature range (-40 degrees C to +85 degrees C). Total generated jitter (TJ) performance is guaranteed to be less than 100pspp. In addition, the unique input isolation on the input multiplexers minimizes the crosstalk-induced jitter contribution to less than 0.7psrms. The SY89537L is offered in an ultra-small 7mm x 7mm, 44-pin MLF(TM) package (QFN JEDEC standard) and the SY89538L is offered in a 10mm x 10mm, 64- pin TQFP. All product datasheets can be found on Micrel's web site, located under the Precision Edge® product line.
