SiT1602BI-72-33E-24.000000 - SiTime

SiT1602BI-72-33E-24.000000 Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal performance?
  SiTime recommends a 4-layer PCB with a dedicated ground plane, and to follow the layout guidelines provided in the SiTime Oscillator PCB Layout Guide (document number: 000-0054-01) to minimize noise and ensure optimal performance.
• How do I handle the oscillator's output enable/disable feature?
  The output enable/disable feature can be controlled by applying a logic high or low signal to the OE pin. When OE is high, the oscillator output is enabled, and when OE is low, the oscillator output is disabled. Ensure that the OE pin is properly terminated and driven to avoid unwanted oscillations.
• What is the recommended power supply decoupling for this oscillator?
  SiTime recommends using a 10nF to 100nF ceramic capacitor in parallel with a 1uF to 10uF electrolytic capacitor to decouple the power supply. This helps to filter out noise and ensure stable operation.
• How do I ensure the oscillator's start-up time meets my system requirements?
  The start-up time of the SIT1602BI-72-33E-24.000000 is typically around 5ms. To ensure the oscillator meets your system requirements, consider using a power-on reset (POR) circuit or a reset signal to synchronize the oscillator's start-up with your system's power-up sequence.
• What is the oscillator's behavior during power-down and power-up cycles?
  During power-down, the oscillator's output is disabled, and the device enters a low-power state. When power is reapplied, the oscillator restarts and resumes operation. Ensure that your system design takes into account the oscillator's power-down and power-up behavior to avoid any potential issues.
