Crystal oscillator circuit in PCB Design - Dashboard Guide

Dashboard Mode - Crystal oscillator circuit

Goal

Understand the key performance metrics of a crystal oscillator circuit and analyze its frequency stability and power consumption.

Sample Data

Test ID	Frequency (MHz)	Power Consumption (mW)	Temperature (°C)	Frequency Drift (ppm)
1	16.000	5.2	25	0.5
2	16.002	5.3	30	0.7
3	15.998	5.1	20	0.4
4	16.001	5.4	35	0.8
5	15.999	5.2	22	0.6

Dashboard Components

• KPI Card: Average Frequency (MHz)
  Formula: Average of Frequency column
  Result: 16.000 MHz
• KPI Card: Average Power Consumption (mW)
  Formula: Average of Power Consumption column
  Result: 5.24 mW
• Line Chart: Frequency vs Temperature
  X-axis: Temperature (°C)
  Y-axis: Frequency (MHz)
  Shows how frequency changes with temperature
• Bar Chart: Frequency Drift (ppm) per Test
  X-axis: Test ID
  Y-axis: Frequency Drift (ppm)
  Shows frequency stability across tests
• Data Table
  Displays all sample data rows for detailed view

Interactivity

Filter by Temperature Range: Selecting a temperature range updates the line chart, bar chart, and data table to show only tests within that range. KPI cards recalculate averages based on filtered data.

Self Check

If you add a filter for Temperature between 20°C and 30°C, which components update?

• Average Frequency KPI updates to average frequency of tests 1, 2, 3, and 5.
• Average Power Consumption KPI updates accordingly.
• Line Chart shows frequency vs temperature only for filtered tests.
• Bar Chart shows frequency drift for filtered tests.
• Data Table displays only filtered rows.

Key Result

Dashboard shows crystal oscillator frequency, power consumption, and stability metrics across temperature tests.
