Micrel Launches New Timing Product Families For PCIe Market

Family Offers Sub-200fs of Phase Jitter for PCIe Clock Applications

San Jose, CA (Marketwired) - Micrel, Inc. (NASDAQ: MCRL), an industry leader in high performance linear and power solutions, LAN and timing and communications solutions, today launched the PL6020xxx and PL6070xxx clock generators along with theSY7557xL clock distribution family that provides extremely low phase noise for the PCI-Express (PCIe) reference clock signals and industry leading output-to-output skew. This new product portfolio exceeds the requirements of the current PCIe Gen1, Gen2, and Gen3 standards and supports SST for EMI reduction. The PCIe product families complement Micrel's growing line of high performance clock generators and clock distribution products. Samples may be ordered by contacting your local Micrel rep or distributor.

Micrel's PCIe clock generators feature 1, 2, 4, or 8 outputs with industry-leading sub-200fs phase jitter and output-to-output skew of 50ps. Spread Spectrum Technology (SST) in thePL6070xxx is also supported for EMI reduction. The clock synthesizers accept a fundamental crystal or reference input of 25MHz and produce output frequencies ranging from 25MHz to 200MHz with 100MHz phase noise performance of -135 dBc at 10kHz offset. In addition, the PCIe clock synthesizers support 2.5V and 3.3V power supply operation offering design flexibility with reduced power dissipation.

Micrel's new SY75576L and SY75578L clock buffers with 4 and 8 outputs, respectively, provide high performance solutions for new and existing PCIe system designs. TheSY75576L and SY75578L offer ultra-low additive phase jitter of sub-150fs with sub-50ps output-to-output skew for stringent PCI Express based server, storage, and networking applications. The products' robust performance enables simplified system level design and PCB layout for quick time to market.

"The newly offered PCIe solutions have expanded our clock and timing product portfolio while offering, yet again, the best performing clock generation and buffer solutions that easily surpass the Gen3 architecture requirements," noted Rami Kanama, vice president, timing and communications business group, Micrel. "The introduction of this new suite of products is indicative of our commitment to being an industry leader in the timing market by offering one of the most complete product lines."

All devices are production released with Industrial temperature range of -40degC to +85degC.The ICs have Green, RoHS, and PFOS compliant packaging. The devices are offered in 6-pin SOT (1 output), 16-pin 3mm x 3mm QFN (2 outputs), 24-pin 4mm x 4mm QFN (4 outputs), or 44-pin 7mm x 7mm QFN (8 outputs) package options.
