The SiT9003 is the world’s lowest power programmable spread spectrum oscillator. It offers a rich set of programmable features – frequency, spread percentage, operating voltage, and frequency tolerance – all in standard industry footprints. These features enable system designers to customize the product for their application, reduce EMI of their design by up to 12 dB and pass environmental compliance without board redesign and expensive metal enclosures. The SiT9003’s industry-best 3.5 mA typical current consumption makes it ideal for portable applications as well as any application that can benefit from lower overall system power consumption.

With its innovative MEMS First™ resonator technology, SiTime is able to mass produce reliable, high performance, MEMS-based silicon timing solutions for a wide variety of applications. The all-silicon SiT9003 comes in four industry standard packages for direct drop-in replacement of traditional quartz oscillators. Like all SiTime products, the SiT9003 low power spread spectrum oscillator is lead free and RoHS compliant

Key Features and Benefits

• Flexible spread options supports up to 12 dB EMI reduction
• Center spread percentage: ±0.25% and ±0.5%
• Down spread percentage: -0.5% and -1.0%
• Spread off option
• World’s best cycle-to-cycle jitter of <30 ps minimizes impact to system timing budget
• 3.5 mA typical power consumption affords more power budget for system designers
• 3 – 7 µA typical standby current enables longer battery life for portable applications
• 3 ms startup time allows the system to go in and out of standby quickly, critical to extending battery life
• Extensive programmability provides designers the opportunity to use the same base product for many designs, minimizing qualification effort and consolidating supplier base
• Any frequency between 1 MHz to 80 MHz
• Selected frequencies between 80 MHz and 110 MHz (eg. PCI Express, Fibre Channel, FireWire-1394 or i.Link) and SATA)
• Operating voltage of 1.8 V, 2.5 V, 2.8 V and 3.3 V
• Frequency tolerance from ±50 PPM to ±100 PPM (when spread is off)
• Four industry standard packages for drop-in replacement of crystal oscillators: 2.5 x 2.0 mm, 3.2 x 2.5 mm, 5.0 x 3.2 mm, 7.0 x 5.0 mm
• Ultra fast lead time of 2 to 3 weeks enhances our customers’ ability to meet demand fluctuations and reduce inventory overhead

SiT9003 Advantages
All of SiTime’s MEMS-based silicon timing solutions have inherent size, height, robustness, reliability, performance and lead time advantages over the competition. Samples can be delivered in 24-48 hours, and production quantities can be delivered with lead times of 2-3 weeks – the shortest in the industry.

SiT9003 Applications
Any electronic devices that require EMI reduction, low power consumption, fast start-up time and small size can benefit by using the SiT9003. Typical target applications include:

• Low power MCU
• PCI or PCI Express
• USB3.0
• Non-baseband clocking in mobile phones (camera modules, multimedia chipsets, etc.)
• Portable gaming devices
• Other handheld applications (eePC, portable test equipment, etc.)
