Use this electronics calculation for a first-pass component, converter, signal, motor, or sensor estimate when the stated operating conditions and units match the device data.

Horizontal total (pixels/line)

Required integer input.

Vertical total (lines/frame)

Required integer input.

Frame rate (Hz)

Required number input.

Calculate total raster pixel clock from horizontal total pixels, vertical total lines, and frames per second, including blanking. The tool evaluates the supplied inputs together and returns the named outputs below; it does not infer omitted operating conditions or change the units shown.^[1]

Pixel clock (Hz)

The resulting pixel clock returned as a number.

• Compact electronics formulas omit some combination of tolerances, temperature drift, bandwidth, loading, parasitics, noise spectrum, nonlinearity, clipping, calibration, layout, and device-specific limits. Typical datasheet values are not guaranteed limits.
• Use finite inputs in the displayed units and preserve more precision than the final presentation requires. Independently verify safety-critical, financial, compliance, or production decisions.

Check the result against the current datasheet and worst-case operating corners, then verify the circuit or measurement with simulation and bench testing where failure matters.

• Video Frame Rate

  Frame rate from pixel clock, total pixels per line and total lines per frame, including blanking.

• Video Line Frequency

  Horizontal line rate from pixel clock and total pixels per line, including horizontal blanking.

• Video Blanking Interval

  Find horizontal and vertical blanking counts by subtracting active pixels or lines from corresponding raster totals.
