BLOCK DIAGRAM VDD CMOS Control Regulator ST Oscillator Circuit Frequency Synthesizer OUT OUT DRV Resonator GND DEVICE OPERATING MODES AND OUTPUTS OUTPUT DURING STARTUP AND RESUME The ULPO supports ≤0.7 µA standby mode for battery-powered and other The ULPO starts up with the output disabled. The output is enabled power sensitive applications. The switching between the active and standby modes is controlled by the logic level on the ST pin. once all internal circuit blocks are active, and logic LOW or FLOAT is detected on the ST pin. As shown in Table 2, logic HIGH at ST pin forces the ULPO into TABLE 2. OPERATING MODES AND OUTPUT STATES “standby” state, causing the output to disable. Upon pulling ST pin LOW, the device enters “resume” state, keeping the output disabled. ST Pin Mode LOW Active FLOAT Active with 200 kΩ internal pull-down HIGH Standby OUTPUT Specified frequency Specified frequency Hi-Z pulled-down with 1MΩ impedence Max Current Consumption Once “resume” state ends, the device output enables. The first clock 60 µA @ 3.072 MHz LOW POWER DESIGN GUIDELINES 60 µA @ 3.072 MHz 1.3 µA pulse after startup or resume is accurate to the rated stability. 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). ACTIVE MODE The ULPO 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 resonator reference. The frequency of the output is factory programmed based on the device ordering code. STANDBY MODE The ULPO 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 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 weakly pulled-down with a 1 + Route noisy PCB traces, such as digital data lines or high di/dt power supply lines, away from the oscillator. + Place a solid GND plane underneath the oscillator to shield the oscillator from noisy traces on the other board layers. MANUFACTURING GUIDELINES + No Ultrasonic or Megasonic Cleaning: Do not subject the ULPO 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. MΩ impedance.
