Thank you jcolao, one last question, Do you know what is the SPI operational mode on the R/D converter?
is it Mode 3 ( CPHA=1 and CPOL=1) ? I appreciate your time.
The AD2s1210 CLKIN and SCLK can work independently. SCLK frequency is dependent on the Vdrive supply with 20Mhz at Vdrive from 4.5V to 5.25V. The AD2S1210 is an SPI compatible interface. To use it as a serial interface, the /SOE pin must be held low and can start input a frequency on the SCLK pin and with pin DB14 as the SDI and pin DB15 as SDO.
For the T33, I will get back to you on that changes as mentioned on the previous post.
I have a similar problem. What is the maximum SPI clk frequency for a 8.192 MHz Crystal? According to the diagram t33 would be around 33us, is this valid? Can I have higher SPI clock than CLKIN?
One last question, what is the SPI Mode for the AD2S1210? is it SPI mode:3? (This mode is used on the AD2S100x models where SDO signal is shifted out on the rising edge SCLK and available on falling edge, but the information on the AD2S1210 is vague)
