SiT8021 Block Diagram** ## **Device Operating Modes and Outputs** The SiT8021 supports a ≤0.7 µA standby mode for batterypowered and other power sensitive applications. The switching between the active and standby modes is controlled by the logic level on the ST pin as shown in the table below. **Table 4. Operating Modes and Output States** |**ST Pin**|**MODE**|**OUTPUT**|**IDD Example**| |---|---|---|---| |LOW|Active|Specified
frequency|60 µA @ 3.072 MHz| |FLOAT|Active
with 200 kΩ
internal pull-down|Specified
frequency|60 µA @ 3.072 MHz| |HIGH|Standby|Hi-Z,
pulled-down with
1 MΩ impedence|1.3 µA| ## **Active Mode** The SiT8021 operates in the active mode when the ST pin is at logic LOW or FLOAT. In the active mode, the device uses the on-chip frequency synthesizer to generate an output from the internal MEMS resonator reference. The frequency of the output is factory programmed based on the device ordering code. ## **Standby Mode** The SiT8021 operates in the standby mode when the ST pin is at logic HIGH. In the standby mode, all internal circuits with the exception of the MEMS oscillator circuit and the ST pin detection logic are turned off to reduce power consumption. While in standby mode, the input impedance of the ST pin is increased to further reduce system-level power consumption. The output driver of the device in the standby mode is pulled-down with 1 MΩ impedance. ## **Output During Startup and Resume** The SiT8021 starts up with the output disabled. The output is enabled once all internal circuit blocks are active, and logic LOW or FLOAT is detected on the ST pin. As shown in Table 4, logic HIGH at the ST pin forces the SiT8021 into the “standby” state, causing the output to disable. Upon pulling the ST pin LOW, the device enters the “resume” state, keeping the output disabled. Once the “resume” state ends, the device output enables. The first clock pulse after startup or resume is accurate to the rated stability. ## **Low Power Design Guidelines** For high EM noise environments, we recommend the following design guidelines: - Place oscillator as far away from EM noise sources as possible (e.g., high-voltage switching regulators, motor drive control). - Route noisy PCB traces, such as digital data lines or high di/dt power supply lines, away from the SiTime oscillator. - Place a solid GND plane underneath the SiTime oscillator to shield the oscillator from noisy traces on the other board layers. ## **Manufacturing Guidelines** - No Ultrasonic or Megasonic Cleaning: Do not subject the SiT8021 to an ultrasonic or megasonic cleaning environment. Permanent damage or long-term reliability issues to the device may occur in such an event. - Applying board-level underfill (BLUF) to the device is acceptable, but will cause a slight shift of few ppm in the initial frequency tolerance. Tested with UF3810, UF3808, and FP4530 underfill. - Reflow profile, per JESD22-A113D. - For additional manufacturing guidelines and marking/ tape-reel instructions, click on the following link: sitime.com/component/docman/doc_download/243manufactuing-notes-for-sitime-oscillators Page 4 of 10 Rev 1.2 www.sitime.com **SiT8021** 1 to 26 MHz, Ultra-Small µPower Oscillator ## **Test Circuit and Waveform** **==> picture [472 x 113] intentionally omitted <==** **----- Start of picture text -----**
