Other Parts Discussed in Thread: DAC3174, CDCE62005, , FMC-DAC-ADAPTER
Hello,
I've got some problems configuring the cdce62005 on the dac3171evm board. I'm using the provided dac3174 gui software. With that I just want to configure the cdce chip's EEPROM. In general my input clock is a 5 MHz clock, and I'm producing three different output clocks 240 MHz each (DACCLK, FIFO, FPGA_CLK). For that I've studied the datasheet and I've written a config file for the tool provided.
My file looks like the following:
CDCE62005 Registers:
x0 x4000002
x1 xC184002
x2 xC184000
x3 xC384000
x4 x4000001
x5 x10001A6
x6 x00BF0B4
xF x0000001
<<DAC3174 Registers:
x0 x4FC
x1 x600E
x2 x3FFF
x3 x0
x8 x6000
x9 x8000
xA xF080
x14 x0
<<
With this I expect the cdce chip to be configured as well as the EEPROM should be written to in unlocked mode according to the datasheet (the last command 0xF 0x1). Unfortunately the tool does not provide a write to EEPROM button and this approach also does not work.
Can someone please tell me what I am doing wrong here? If this is not possible, can you please tell me how to configure the chip's EEPROM?
Another approach would be to write an own small program to send the commands via the USB port. For that I would need to know the protocol which I would have to send to the virtual com port which can then be parsed by the onboard Altera PLD. Otherwise would it be possible to reprogram the PLD with the help of the programmer pins?
Thank you for your help,
Lars
