We intent to apply ADV7511W as HDMI transmitter (shall replace an obsolate one).
We miss a RESET pin at IC for reproducable start condition of internal state machine.
Unfortunately there is no Reset pin on the ADV7511. There are 2 ways to 'reset' the part. 1) power cycle, not circuit friendly in my opinion. 2) run a reset script which puts all the registers back into the power up default state. I can give you this script if you decide to go down this path.
Normally we don't reset the part, once initialized we just modify what is needed to handle format changes.
Thanks for your information.
Standard power-up should be sufficient for the start conditions.
Additional reset can be made via I2C with some register settings (summarized in a script).
It would be helpful to get that script.
The first script in this file initializes the ADV7511 to power up defaults. It's over kill but covers all the bases.
thanks a lot for your support.
The script was downloaded. Fine -it contains a “RESET” emulation and moreover registering for other working modes.
We will test it if our new hardware will be available.
