&lt;p&gt;This RTC IC has been specially designed for ultimate low current
consumption of typically 60 nA @ VDD 3.0V for 32.768 kHz XTAL mode.
Additionally, there is an RC-Mode consuming only 17nA and an autocalibrated
RC-mode consuming 22nA which permits to operate this RTC
module several hours at Backup Supply Voltage using low-cost MLCC.
The very small SMT ceramic-package combines the 32.768 kHz crystal
unit with the CMOS-based oscillator and real-time-clock IC. &lt;/p&gt;</description>

<description>&lt;h3&gt;Oscillators (Generic)&lt;/h3&gt;
&lt;p&gt;These are &lt;b&gt;active&lt;/b&gt; oscillators, which require a power source to generate their clock output. Most oscillators are configured to generate a set frequency (e.g. 16MHz).&lt;/p&gt;
&lt;p&gt;They have four pins: power, ground, output, and an enable input.&lt;/p&gt;</description>

<description>&lt;h3&gt;Resonators (Generic)&lt;/h3&gt;
&lt;p&gt;Ceramic resonators are clock-generating components, often used to control timing in microcontrollers. They usually have 3 pins: two pins for oscillation, and one pin for ground.&lt;/p&gt;
&lt;p&gt;Compared to crystals, resonators have worse tolerance, but are usually much cheaper. Plus, they have built-in load capacitors!&lt;/p&gt;
&lt;p&gt;These devices are used on boards like the &lt;a href="https://www.sparkfun.com/products/11114"&gt;Arduino Pro 8MHz&lt;/a&gt; and &lt;a href="https://www.sparkfun.com/products/11113"&gt;Arduino Pro 16MHz&lt;/a&gt;.&lt;/p&gt;</description>

<description>&lt;h3&gt;Micro Crystal Switzerland - RV-1805-C3 - Extremely low power RTC module&lt;/h3&gt;
&lt;p&gt;This RTC IC has been specially designed for ultimate low current
consumption of typically 60 nA @ VDD 3.0V for 32.768 kHz XTAL mode.
Additionally, there is an RC-Mode consuming only 17nA and an autocalibrated
RC-mode consuming 22nA which permits to operate this RTC
module several hours at Backup Supply Voltage using low-cost MLCC.
The very small SMT ceramic-package combines the 32.768 kHz crystal
unit with the CMOS-based oscillator and real-time-clock IC. &lt;/p&gt;</description>
