Cannot load settings from EEPROM on AD9544

Question

I've created a working configuration in ACE and tested it on the evaluation board. I converted it to a bin file using the python script, which works although it gives a number of warning messages:

Checksum is: 0xb4206fd 
 I removed the EEPROM and put it in an external programmer and verified that the bytes were copied. Next I put the EEPROM back into the evaluation board, and set the M3 jumper as described in the wiki: 
 
 This lights up a red LED and puts TP603 to 1.8V, but on power up the PLL has no output. If I power up, then remove the M3 jumper, I can read back the registers in ACE, which are default. 
 I'm not sure what else to try. Perhaps I have made the bin file incorrectly?

HI, 
 
 I was able to set DPLL1 in internal zero delay with feedback from OUT1A=7.919kHz in Configuration Wizard: 
 
 Try it.

HI, this morning I took an AD9544 eval board and I took out the R319=50 ohm, so it accepts 1.8V CMOS 7.908kHz at REFBB. I also modified the USB EEPROM, so now the board is seen by ACE as an AD9545 eval board. I then used ACE to configure the AD9544 with your cso file and I was able to see at OUT0A the 7.908kHz clock. DPLL0 locked. I then used a python script to upload the AD9544 configuration into the EEPROM. I powered down the board, plug the jumper on M3 to make it high and powered back up the board. I could see on the scope OUT0AP, so the EEPROM downloaded correctly. I then created a new python script that creates an AD9544 bin file. What you have creates an AD9545 bin file. I created a bin file. I then read the EEPROM with another script and I compared the new bin file against the target bin file and they were identical. I then ran another script that writes the EEPROM using the USB chip on the eval board with the bin file. I again cycled the board and the OUT0AP showed the right clock, meaning the EEPROM had the right value and downloaded correctly. I also read the AD9544 registers and they were identical with the target ones. I'm sharing the scripts for you to see the procedures I'm following. The problem you have is they use an internal library of read/write registers function that I cannot share. But you can use as an example for you to write a controller program to upload the EEPROM with the correct values. The script AD9544_download_config reads the cso file and writes the registers into the AD9544, calibrates the analog PLLs and synchronizes the outputs. You do not need to synchronize the outputs because you use Reference Sync function.

So the cso file is an AD9545 file and we need to download it into the AD9544 State of board jumpers: -P501 is plugged in, so USB EEPROM can be accessed by USB chip and the board can be recognized by Windows -P502 is plugged in, so the USB EEPROM is write protected -P504, P511, P510 and P503 plugged between pins 2 and 3 (SCLK and SDIO), so PC can use SPI to access the AD9545 -P603 and P602 plugged between pins 2 and 3 (DUT), so the AD9545 can access the EEPROM through I2C -P601 taken out, so the EEPROM is not write protected -at P604, plug jumpers for M1 and M2 between middle pin and VDD label, so the I2C lines have pull up resistors: MP1_PULL between 4 and 5, MP2_PULL between 7 and 8.

HI, 
 "e ven when the REFBB input is power off. there is 7908hz square wave at OUT1B and 55.36MHz at OUT1A. 
 But we wan the two signals change according to REFBB " 
 The AD9544 was designed to always maintain an output even when the reference clock becomes invalid. There is a functionality called muting, which I recommend you take a look. The controller can get an interrupt when the DPLL enters holdover (because the reference clock became invalid) and then it can manually "mute" the desired outputs, that is it forces them to 0V. 
 There is then the functionality called "automatic output unmuting" that can automatically unmute the outputs (basically get them going again) after the DPLL exits holdover (basically when the reference becomes back valid). So you must manually mute the outputs, but they can get on again (i.e. unmuted) automatically. See page 65 in rev C AD9545 data sheet. 
 I looked at the cso file you sent. It seems OK. The offset tolerance on REFBB is 1000 ppm, which is pretty big, but if this works for you and the DPLL stays locked continuously, then you are good.

HI, 
 you need to enter in the register map and change the registers that manage the automatic output unmuting there. 
 About storing the configuration into EEPROM: there is an application note that describes the EEPROM management process. ACE does not deal with the EEPROM. On your board that you'll design, you need to create a program for your controller that uploads the AD9544 configuration into EEPROM and then, when you power down/up the board, the AD9544 downloads its configuration from the EEPROM. See AN-2072: 
 https://www.analog.com/media/en/technical-documentation/app-notes/an-2072.pdf

Hi feitianlaoshu, 
 Programming the USB EEPROM to make the board be seen as an AD9545 helps ACE to see the AD9544 on the eval board as an AD9545. It does not help with the EEPROM. 
 I'm glad you got the DPLL to lock. 
 The fact that you burned the EEPROM with the bin file I sent and then the AD9544 did not generate anything, it means to me that the board was not configured correctly to have the AD9544 download the EEPROM. 
 I would start with the oscilloscope probe put on pin 5 of P604 (it is as if you put the probe on M1 pin of the AD9545). This senses the SCL pin of the EEPROM. This supposes R629=0ohm is mounted. Then put the second probe on pin 8 of P604 (it is as if you put the probe on M2 pin of the AD9545). This senses SDA pin of the EEPROM and supposes R630 is mounted. 
 See if when AD9545 is powered up, the EEPROM download starts.
