EM Microelectronic (www.emmicroelectronic.com) has introduced the EM1564, which integrates a 32.768 kHz tuning fork crystal and a CMOS circuit in a 10-pin SMD package. March 30, 2006 EM ...

Oscillators are as ubiquitous—and, some might argue, as important—as power supplies in electronics systems, finding use in anything that needs a timing signal, from digital watches to TVs and PCs.

Fig 1. This Pierce-series resonant oscillator can reliably start at supply voltages as low as 2.4 V. It also draws very low current, ensuring long battery life. Fig 2. An oscilloscope photo shows the ...
