Silicon Labs premiered the industry’s most highly integrated MEMS-based oscillators designed to replace general-purpose crystal oscillators (XOs) in cost-sensitive, low-power and high-volume industrial, embedded and consumer electronics applications such as digital cameras, storage and memory, ATM machines, point-of-sale equipment and multi-function printers.
The new Si50x oscillators are based on the company’s patented CMEMS technology – the first to enable MEMS structures to be built directly on top of standard CMOS wafers in high-volume fabs, resulting in fully integrated, highly reliable monolithic ‘CMOS+MEMS’ IC solutions.
According to Silicon Labs, CMEMS technology enables guaranteed data sheet performance with 10 years of frequency stability including solder shift, load pulling, VDD variation, operating temperature range, vibration and shock. This guaranteed operating life performance is 10 times longer than typically offered by comparable crystal and MEMS oscillators.
The new oscillators tightly couple the MEMS resonator with CMOS temperature sensor and compensation circuitry, ensuring a highly stable frequency output in the face of thermal transients and over the full industrial temperature range. The end result is a predictable, reliable frequency reference over the long operating life spans of industrial and embedded applications. CMEMS resonators are passively compensated, using materials with offsetting temperature behaviours in the design.
The Si50x devices support any frequency between 32 kHz and 100 MHz. Frequency stability options include ±20, ±30 and ±50 ppm across extended commercial (-20°C to 70°C) and industrial (-40°C to 85°C) operating temperature ranges.
The CMEMS oscillators also offer extensive field- and factory-programmable features including low-power and low-period jitter modes, programmable rise/fall times and polarity-configurable output-enable functionality.
The devices are available in three industry-standard 4-pin DFN package sizes: 2 x 2,5 mm, 2,5 x 3,2 mm and 3,2 x 5 mm.
