Attached and linked are several files supporting the development of systems using the ADV7180.
Hello,
So is the following correct ?
Setup 1: NTSC connected directly to Television
Setup 2 : NTSC -> ADV7180 -> STM32F769i Eval evauation board -> monitor.

Could I ask another question?
When we don’t have input signal to ADV7180 at setting of Square Pixel Mode Address 0x01[2]=H,Can we let ADV7180 output Square pixel clock (24.5454MHz) ?
Current status is below. ADV7180 outputs square pixel…
Hi Aydin,
Those registers optimise the ADV7180 and the values were determined during the evaluation of the ADV7180.
They must be programmed when using the ADV7180.

Could you please advise me it is in specification of ADV7180 or not, first of all?
The customer said that he can see 2nd pixcel to 720 pixcel on the output of ADV7180. But he can't see 1st pixcel on the output of ADV7180. It seems like masked…
Hi,
ADV7180 Software on the Analog Devices FTP Site details are provided in ADV7180_Installation_Guide_4.0.pdf on Page4 at ez.analog.com/.../adv7180-design-support-files
And also please make sure with below thing,
1)As per expert comment,disconnecting…
For ADV7180, The crystals in ADV7180 systems will start oscillating when powered up even before the ADV7180 is programmed, because chip is powered up using active High signal on PWRDWN pin.
Old versions of the ADV7180 datasheet show two capacitors connected to the VREFP and VREFN pins on the ADV7180. Modern ADV7180 datasheets show one capacitor between the VREFP and VREFN pins.
Which is the correct setup?
The ADV7180 cannot free-run with a color-bars pattern. However it can free-run with a flat color screen. The color of this screen is user configurable.
See 'Color Controls' section of the ADV7180 datasheet for a description of how to set the…
Dear Sir/Madam,
During a hardware reset (i.e. the reset pin of the ADV7180 held low) the digital outputs from the ADV7180 can become unstable this includes the LLC clock output. This is due to the digital core of the ADV7180 going into an undetermined…
