MEMS-based oscillator family aimed at Tablet PCs and E-Books

April 15, 2011 // By Phil Ling
A complete portfolio of MEMS oscillators for Tablet PC and E-Book reader designs is now available from MSC. The solutions, which are based on SiTime's SiT8003 Low Power MEMS Oscillator platform, are claimed to be approximately 30% thinner than quartz and offer up to 10 times better robustness to shock and vibration.

The programmable MEMS oscillators can be configured for use with applications processors, USB2.0 transceivers, platform controller hubs (PCHs), HDMI SoCs, audio codecs and camera modules. The device features a low current consumption of only 3.5 mA in active mode and less than 5 µA in standby mode.

Any frequency between 1MHz and 110MHz with 5 decimal places of accuracy can be programmed. The SiT 8003 offers ±25 PPM frequency stability over -20ºC to +70ºC operating temperature range and is available in a tiny 2.5 mm x 2.0 mm package. Configurable operating voltages of 1.8, 2.5, 2.8 or 3.3V are available.

Samples of the various MEMS oscillators are usually available within 48 hours and production quantity lead times are said to currently be 3-5 weeks.
