Hi, team
I am using the 903/904 serdes pair to transfer image.
I have the following troubles:
1.The 903's MODE=H and 904's MODE=L, according to the D/S, the mcu on the 903 side should can access the registers of 903 and 904, but it can not access the 904's registers.
the default i2c address is 0x58 for 903 and 0x60 for 904, and I2C pass through is enable by default !
2. for the 0x0C register of 903, according to the d/s, the LINK DETECT=1 when Cable link detected, but in fact LINK DETECT=0 when cable is linked and is 1 when cable not linked, the datasheet is wrong or the IC is in wrong status?
3. the 903's PCLK_AUTO = 1 by default, when no valid pclk input to the 903, the 903 output internal 25 MHz to 904, but when 903's MODE=0, 904 can not detect the 25MHZ pclk, when when 903's MODE=1, 904 can detect and output 25mhz pclk
Thank you
Best regards
