Can you tell me about ADV7391 f CLKIN 27 MHZ Frequency Stability? thanks.
Normally the crystal we use are spec'd at 50ppm but 100 ppm should be OK for SD. Here's a reference to a crystal we've used in various boards.
I'm not sure where this question is coming from. The ADV7391 just uses the supplied video clock to output the analog signals. Normally the source will be referenced from a crystal oscillator or crystal based clock. These normally are <100ppm over temperature with low jitter. Programmable clocks have higher jitter and frequency tolerance.
Thank, so using the SD video the input clock SPEC is 27MHz + /-100ppm?
Are there any document?
