Micrel Expands ClockWorks™ Products With High Performance FLEX2 Custom-Configurable Clock Generator Family

Dual PLL Device With Less Than 200fs, Optimized for Ultra-Low Jitter, Ultra-Low Crosstalk, Enhanced Power Supply Noise Rejection

SAN JOSE, CA--(Marketwire - Oct 29, 2012) - Micrel, Inc. (NASDAQ: MCRL), an industry leader in high performance analog and high-speed mixed signal, LAN, and timing and communications solutions, announced a new highly configurable dual PLL clock generator optimized for ultra-low jitter, excellent crosstalk isolation and enhanced power supply noise rejection. The SM803xxx family achieves less than 200 femto-second (fs) RMS phase jitter with twelve differential or single-end outputs for frequencies up to 850MHz. FLEX2 supports very demanding applications requiring numerous frequencies, high fan-out, and ultra-low jitter on a single IC. This includes 10/40/100 Gigabit Ethernet, SONET/SDH, CPRI/OBSAI, Fibre Channel, SAS/SATA, and high speed clocking for FPGA and SerDes. Factory configurable using fuse-based one-time programmable (OTP) memory, FLEX2 delivers a customized, quick turn and high performance clocking solution that shortens prototyping time and end system design cycle.

"Following through with Micrel's strategy to expand our Clock and Timing products with high performance and flexible products, we are excited to announce the Clockworks FLEX2 family," stated Rami Kanama, vice president for the timing and communications product group, Micrel. "As the industry's lowest jitter custom-configurable dual PLL clock synthesizer, the SM803xxx enhances frequency flexibility and quickly delivers a fully customized clocking solution. With its ultra-low jitter and integrated fan-out capability, FLEX2 improves system performance and lowers both BER and SNR, offering customers a much needed system jitter budget for high speed applications."

The SM803xxx product is currently available in production quantities and sampling to customers. Pricing is dependent upon configuration, for specific pricing contact your local sales representative. For more information on Micrel's Clockworks FLEX products go to: Clockworks
