SiTime Debuts SiT8503 a kHz Frequency Silicon MEMS Oscillator
By Shamila Janakiraman
SiTime Corporation specializing in MEMS-based silicon timing solutions announced the introduction of the SiT8503 a kHz frequency silicon MEMS oscillator for audio, microcontroller and other industrial applications.
According to company sources it offers a broad portfolio of Silicon MEMS-based, megahertz frequency, differential oscillators, clock generators, VCXOs, spread spectrum timing products and embedded resonators. The SiT8503 adds kilohertz or kHz frequency timing solutions to this portfolio serving as a one-stop silicon timing provider.
Piyush Sevalia, vice president of marketing at SiTime said, “The SiT8503 leverages its silicon MEMS technology and programmable architecture to offer many unique features that are not available from quartz, such as frequency and voltage configurability, small size, low power and extreme ruggedness.”
“SiTime’s growing customer base is rapidly replacing their quartz oscillators with Silicon MEMS solutions. In addition, our industry-leading portfolio of silicon timing solutions is enabling us to become a strategic supplier of timing components to large OEMs worldwide,” Sevalia added.
The main features of the SiT8503 include programmable support for any frequency between 200 kHz and 1000 kHz with accuracy up to 5 decimal places. This supports a wide range of applications and allows the customer to optimize the frequency for their application.
The device features configurable operating voltages of 1.8V, 2.5V, 2.8V or 3.3V which eliminates the need for expensive, external, level translators and minimizes the need for additional regulators in the system, thereby reducing cost. The device is highly rugged not possible with quartz, enabling it to provide a shock resistance of up to 50,000 G and vibration resistance of up to 70 G.
The configurable frequency stability of ±20PPM, ±25PPM, ±30PPM or ±50PPM helps the customer to optimize the product for the best timing margin in their system resulting in full drop-in replacement of quartz solutions in all four industry-standard surface-mount packages. Long battery life is ensured by minimum current consumption of less than 10µA in standby mode.
SiTime sources added that samples of the SiT8503 are available now and volume production will be start from September. 30, 2010. The company specializes in the change over from quartz products to MEMS-based silicon timing solutions. SiTime’s products form the core of high-performance electronics such as FTTH and Passive Optical Networking or PON equipment, 10-Gigabit Ethernet switches, computing and storage servers as well as high volume applications such as digital cameras, LCD HDTVs, desktop and portable computers, set top boxes, multi-function printers and solid-state drives.
