We are using TFP401A in one of our products. The output of PCLK from TFP401A is as below. It appears that nether the pulse width nor the frequency is uniform. Is this normal for RGB pixel clock output with HDMI/DVI input?
Thanks

Was the output clock ever captured using a real-time oscilloscope? Can you provide those captures?
The timescale is too large to capture a clock, what does the waveform look like with a timescale of say 50ns/Div? Is this capture from an actual real-time scope or is this from an analyzer front-end? Can you capture the SYNC signals as well (Timescale should change)?
