SiTime Unveils Silicon MEMS Timing Solutions for Tablets, E-book Readers

SiTime Corp. has launched a complete portfolio of MEMS oscillators for tablet PCs and e-book readers. These solutions, all of which are based on SiTime’s SiT8003 Low Power MEMS Oscillator platform, provide clocking for every major functional block in tablet PCs and e-book readers. The SiT8003 is 30 percent thinner than quartz and offers 10 times better robustness to shock and vibration.

“Tablet PCs and e-book readers are one of the fastest growing segments in the electronics industry and are expected to ship over 200 million units by 2014. SiTime’s low-power, programmable MEMS oscillators already provide the timing reference for many tablet PCs and e-book readers,” said Piyush Sevalia, SiTime’s vice president of marketing. “Exciting, high-volume applications such as tablet PCs have rapidly adopted SiTime’s Silicon MEMS timing solutions over legacy quartz products, as our solutions offer the best size and robustness, unprecedented flexibility, and the lowest cost of ownership.”

SiTime’s SiT8003 low-power programmable MEMS oscillator can be configured to drive many different devices within a Tablet PC and E-Book Reader. Some common configurations are highlighted below:
• SiT8003AC-12-18S-26.00000 for the Applications Processor and USB2.0 transceiver
• SiT8003AC-12-33S-14.31800 for the Platform Controller Hub (PCH) chip
• SiT8003AC-12-33S-22.57920 for the HDMI SOC
• SiT8003AC-12-33S-24.57600 for the audio CODECs
• SiT8003AC-12-33S-27.00000 for the camera module

The SiT8003 offers the best combination of low power, small size and high performance for tablet PC and e-book reader designs. The device consumes 3.5mA in active mode and less than 5µA in standby mode, offers ±25ppm frequency stability over -20ºC to 70ºC operating temperature and is available in a tiny, 2.5x2mm package.

SiTime’s SiT8003 offers configurable rise and fall times at no additional cost. By controlling the rise and fall times of the various clocks within the system, the designer reduces system EMI and can meet environmental compliance more easily, cost-effectively and without any design changes.
