Micrel Intros Configurable Dual PLL Clock Generator

Micrel (News - Alert) Inc., a global manufacturer of IC solutions for the worldwide high-performance linear and power, LAN and timing and communications markets, recently introduced a new configurable dual PLL clock generator called SM803xxx, belonging to the company’s ClockWorks product family.

According to the company, ClockWorksFLEX family of ultra-low jitter, single-PLL (FLEX) and dual-PLL (FLEX2) clock synthesizers enables custom-configured best-in-class reference clock generation solutions for networking, telecom, storage, wireless base-station and broadcast video applications.

All the products in the SM803xxx series reach less than 200 femto-second (fs) RMS phase jitter with twelve differential or single-end outputs for frequencies up to 850MHz. In addition, the FLEX2 backs major of the applications requiring numerous frequencies, high fan-out, and ultra-low jitter on a single IC – including 10/40/100 Gigabit Ethernet, SONET/SDH, CPRI/OBSAI, Fiber Channel, SAS (News - Alert)/SATA, and high-speed clocking for FPGA and SerDes.

"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.

Kanama said the SM803xxx enhances frequency and flexibility, and quickly delivers a fully customized clocking solution. And 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.

FLEX2 utilizes fuse-based one-time programmable (OTP) memory to offer a customized, quick turn and high-performance clocking solution that can cut short the prototyping time and end system design cycle.

The new SM803xxx product is currently available in production quantities and sampling to customers, and the pricing is dependent upon configuration.

Micrel has its corporation headquarters and state-of-the-art wafer fabrication facilities in San Jose, CA (News - Alert), and offers advanced mixed-signal, analog and power semiconductors, high-performance communication, clock management, Ethernet switch and physical layer transceiver ICs.
