tablet-overview

Tablets are the new revolution in personal computing. All forecasts indicate that tablet volumes will increase significantly and these platforms may even replace personal computers in consumer and enterprise applications. Most tablet designs require the following:

  • Small size, thin
  • Low power consumption
  • Robustness to shock and vibration

 

SiTime offers a complete portfolio of timing solutions that are targeted at Tablets. Our MEMS oscillators provide clocks to every functional block in a tablet, while simultaneously providing compelling value propositions such as:

  • Wide Frequency Range (up to 200 MHz)
  • Small Size (as small as 2.5 x 2.0mm, as thin as 0.25mm)
  • Low Power Consumption (2.5 μA in standby, 3.5 mA in active mode)
  • Short Lead Time (2-3 weeks)
  • Best Robustness (Up to 50,000 G shock and 70 G vibration)
  • Best Programmability for custom frequency, rise/fall time control, etc.
