Micrel Launches Industry's Smallest LVDS 1:2 Fanout for Low Jitter Applications



SAN JOSE, Calif., May 24 -- Micrel Inc. (NASDAQ:MCRL), an industry leader in analog, high-bandwidth communications and Ethernet IC solutions, today added to its family of high-speed clock and data distribution ICs with the introduction of the SY89835U, a 1:2 LVDS fanout buffer featuring Internal Termination and fail safe input in a tiny 2mm x 2mm 8-pin foot print. Total jitter is guaranteed to be less than 10pspk-pk and the skew is guaranteed to be less than 20ps over supply voltage and temperature, making this part ideally suited for clock distribution or data distribution applications in SONET, Fibre Channel clock or Gigabit Ethernet systems. The SY89835U is currently available in volume with prices starting at $1.69 for 1K quantities.

"Micrel's SY89835U clearly outperforms the closest fail-safe input alternative on the market today," said Thomas S. Wong, vice president high bandwidth products for Micrel. "Our solution is 55 percent smaller, four times faster and 30 percent less expensive, making it the ideal choice for today's most demanding low jitter applications."

The SY89835U features guaranteed AC performance over temperature and voltage including DC-to-more than 3.2Gbps throughput, 210ps typical propagation delay (IN-to-Q), less than 20ps within-device skew and less than 150ps rise/fall times. The IC includes fail-safe input that prevents metastable conditions when the clock or data input fails to a DC voltage or is not present, thus forcing the differential input to the same potential. The IC's 100 ohm internal termination across the input pair eliminates stubs and reduces input reflections. It also features an ultra-low jitter design with less than 1psRMS cycle-to-cycle and Random Jitter (RJ) and less than 10psPP Total Jitter (TJ). The SY89835U operates from a 2.5V supply, over the -40 degrees C to +85 degrees C industrial temperature range and is available in small 8-pin 2mm x 2mm MLF(R) packaging.
