Product Summary
Among SiTime's MEMS clocks, this product group has an attractive feature of ultra-low power consumption.
We can offer products in ultra-small 1.5 x 0.8 mm size CSP packages and products with current consumption on the μA order.
Up to 90% lower power consumption and 40% smaller size compared to crystal oscillators.
Since it is a programmable product, any oscillation frequency (up to 6 digits after the decimal point) can be shipped according to the customer's specifications.
Recommended for such applications
Ideal for applications that require low power consumption and reduced board space.
・Smart meters ・Medical equipment (portable) ・Sensor devices ・FA cameras
・Reference clock for AFE ・Mobile devices ・Wearable devices (smart watches, etc.), etc.
