SiTime Introduces World's Smallest Lowest Jitter Programmable Oscillator.SiT8102 Offers Sub 1 ps RMS Phase Jitter A flicker or fluctuation in a transmission signal or display image. The term is used in several ways, but it always refers to some offset of time and space from the norm. For example, in a network transmission, jitter would be a bit arriving either ahead or behind a standard clock cycle in a 2.5 x 2.0 mm Package Suitable for High Speed Serial Communication, Video, and Storage Applications SUNNYVALE, Calif. -- Please replace the release dated Sept. 24, 2007 with the following corrected version due to multiple revisions. The corrected release reads: SITIME INTRODUCES WORLD'S SMALLEST LOWEST JITTER PROGRAMMABLE OSCILLATOR oscillator Mechanical or electronic device that produces a back-and-forth periodic motion. A pendulum is a simple mechanical oscillator that swings with a constant amplitude, requiring the addition of energy at each swing only to compensate for the energy lost because of air SiT8102 Offers Sub 1 ps RMS Phase Jitter in a 2.5 x 2.0 mm Package Suitable for High Speed Serial Communication, Video, and Storage Applications SiTime Corporation, the world's leading innovator of MEMS-based timing solutions, has begun sampling a family of low jitter programmable oscillators targeting the high speed serial communication and storage markets. The SiT8102 oscillators offer sub 1 ps rms phase jitter performance over an integrated bandwidth. These oscillators are offered over a wide frequency range of 1 MHz (MegaHertZ) One million cycles per second. It is used to measure the transmission speed of electronic devices, including channels, buses and the computer's internal clock. A one-megahertz clock (1 MHz) means some number of bits (16, 32, 64, etc. to 200 MHz in a smaller footprint, thinner package and lower cost as compared to quartz-based oscillators or quartz crystals and associated high performance clocks chips. Introducing the SiT8102 All SiT8102 oscillators contain the world's most pervasive MEMS (MicroElectroMechanical Systems) Tiny mechanical devices that are built onto semiconductor chips and are measured in micrometers. In the research labs since the 1980s, MEMS devices began to materialize as commercial products in the mid-1990s. resonator resonator /res·o·na·tor/ (rez´o-na?ter) 1. an instrument used to intensify sounds. 2. an electric circuit in which oscillations of a certain frequency are set up by oscillations of the same frequency in another and a CMOS IC CMOS IC Complementary Metal Oxide Semiconductor Integrated Circuit that controls, drives, and frequency multiplies the MEMS resonator. This advanced architecture is one time factory programmable and generates any frequency between 1 MHz and 200 MHz with only +/-50 or +/-100 ppm frequency error inclusive of inclusive of prep. Taking into consideration or account; including. aging, power supply variation, and shock. Product family options also include: commercial and industrial temperature ranges; operating power supplies from 1.8 V, 2.5 V, or 3.3; and a power down mode or an output disable mode for lower power consumption. "Leveraging the success of the first generation SiT8002 product family, the new SiT8102 product family from SiTime sets a new standard for the performance of all programmable oscillators while expanding the reach of MEMS oscillators into applications such as high speed serial communications, high-end video, and high-speed memories, that were exclusively serviced by quartz-based products," said John McDonald, VP Marketing at SiTime Corporation. "By leveraging the infrastructure of the $200 B semiconductor industry, SiTime is able to bring the highest performance, smallest, and thinnest timing products to market." SiT8102 Advantages Programmable oscillators offer immediate frequency generation and lead-time benefits because they are stocked in high volume and frequency programmed on demand. However, traditional programmable oscillators have been limited to applications that could accept between +/-70 ps p-p jitter (10 ps rms) to +/-250 ps p-p jitter (30 ps rms) depending on the frequency. The SiT8102 oscillator has much better jitter performance as compared to traditional programmable oscillators, evidenced by the performance table below. [TABLE OMITTED] This performance advancement now allows SiTime's programmable oscillators to compete with traditional fixed-frequency quartz oscillators while still retaining the short lead times and high volume availability. All of the customary benefits of SiTime's MEMS First(TM) and EpiSeal(TM) processed resonators apply to the SiT8102 product family. These benefits include: excellent frequency performance over age, temperature, shock, vibration, and constant acceleration. Inside the package the resonator measures a mere 0.8 x 0.6 mm. As a result the oscillator family is able to be packaged in a tiny 2.5 x 2.0 x 0.8 mm QFN-type IC package. Larger industry standard package sizes are also available. The combination of excellent jitter performance, tiny size, and mechanical robustness of the SiRes[TM] MEMS resonators, and low-cost IC packages compatible with quartz-based oscillator footprints make the SiT8102 oscillators ideal clock references for USB USB in full Universal Serial Bus Type of serial bus that allows peripheral devices (disks, modems, printers, digitizers, data gloves, etc.) to be easily connected to a computer. 2.0 HS, Firewire, Fibrechannel, SATA (Serial ATA) A serial version of the ATA (IDE) interface, which has been the de facto standard hard disk interface for desktop PCs for more than two decades. The original Parallel ATA (PATA) interface was launched in 1986. , PCI-Express, Gigabit Ethernet, and other high-speed serial communication protocols. Pricing and Availability The SiT8102 is currently available for limited sampling, and will be widely available for sampling beginning November 1st, 2007. All SiT8102 package types are very competitively priced as the cost structure of MEMS based oscillators is lower than quartz.
