Does AD9219 work normally without SPI configuration by default register value ?
Or is software reset required?
Now, AD9219 dosen't work without config...
I did not connect SPI to FPGA. Because it is not necessary to change a default value.
how can I get rule of name about ADC or DAC, such as ad9268,ad9219,ad9239,ad9244 and so on?
Thanks for working with the AD9219.
I may not have made myself clear : I have two separate AD9219 chips, I understand within one chip the channels are synchronized, but how can I synchronize two chips ?
does anyone know the differential input impedance at ~5 MHz of the AD9219?
Our measurement suggest it is about 1.5k. Can you confirm this?
I am to use the AD9219 quad ADC in a new design.
I will use only three of the four ADCs and I would like to turn the fourth in power down mode.
The datasheet rev. E is not clear to me, it seems programming the 0x22 register could do the job…
By new configuration, I meant that you configuring the device (AD9219) differently, to mix your base band signal to 1.4 GHz.
The provided reference design is using the DDS as data source:
Xil_Out32((CF_BASEADDR + 0x04), 0x00000); Xil_Out32((CF_BASEADDR…
I believe you have the 65MSPS version. According to the datasheet, the first 4-bit nibble contains the speed grade information. As such, Register 0x02 = 0x01 indicates the 65MSPS device.
Thank you for considering the AD9219.
Hello ADI team,
Is it works when apply 1.2GHz to AD9219 DACCLK_x?
We'd like to use in Normal Mode (baseband mode).
Should we do something around the chip?
