I am using ADV7511 as HDMI tx in one of my project. The input to the ADV7511 is (SD-SDI/HD-SDI) driven by FPGA and s/w image running on FPGA does all required I2C configurations.
I could bring up all my HD formats and SD formats except NTSC. I am using similar configuration sequence for both PAL & NTSC, PAL works fine but not NTSC. Can somebody please help me out in resolving this issue?
I have attached config sequence which i used for PAL and NTSC. I am referring "ADV7511 Low-Power HDMI 1.4 Compatible Transmitter with Audio Return Channel - PROGRAMMING GUIDE" for configuration (http://www.analog.com/static/imported-files/eval_boards/ADV7511_Programming_Guide.pdf)
