Hi all, I am now studying the MT2060 silicon tuner driver with the use of TDA10046A. And my development board has no EEPROM for both TDA10046A and MT2060. I found that in the linux-2.6.19 source tree, all the DVB-T devices which used MT2060, will try to load the IF1 value from a EEPROM. But how about if I have no EEPROM? Do I need to manually calculate the IF1 value? If so, how? Is it very complicated? Thanks. Best regards, Lo Chun Chung ECE-DHT@ASTRI.

I assume the MT2060 is similar to the MT2050. In this case, the IF center frequency is defined by the SAW filter on the board. The TDA10046 driver currently supports 2 "direct" IF frequencies: 36.125MHz and 36.1667MHz. IF you have a down converter like the tda9889, you can use either 5.1667MHz or 4.0, 4.5, 5.0MHz depending on the bandwidth. These can be chosen in the tda1004x_config structure. It is possible to add other frequencies, but yneed to extend some tables. The equations are in the datasheet.
