SiTime Corp. introduces a portfolio of MEMS oscillators for tablet PCs and E-book readers. These solutions, based on SiTime's SiT8003 Low Power MEMS Oscillator platform, provide clocking for every major functional block in the tablet PC and E-book reader. The SiT8003 is 30 percent thinner than quartz and offers 10 times better robustness to shock and vibration, improving the aesthetics and lifespan of tablet PCs and E-book readers.

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: 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; and SiT8003AC-12-33S-27.00000 for the camera module.

SiT8003

The SiT8003 oscillator is ideal for portable devices, specifically tablet PCs and E-book readers.

The SiT8003 boasts 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 5?A in standby mode, offers ㊣25PPM frequency stability over -20∼C每70∼C operating temperature and is available in a tiny, 2.5x2.0mm 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.

The SiT8003 offers frequency between 1 and 110MHz with 5 decimal places of accuracy. A customized clock frequency can be used for increased performance (over-clocking) or cheaper testability. Its configurable operating voltage is 1.8, 2.5, 2.8 or 3.3V. It also operates in industrial (-40∼C每85∼C) and extended commercial (-20∼C每70∼C) temperature range and available in four industry-standard packages, enabling replacement of quartz oscillators with no design changes.

The devices are available in production now, and pricing is available upon request. Sample shipments will be available in 24每48 hours with production lead times of three to five weeks.
