Part Number: AFE7225 Tool/software: Hello, I've noticed that in some other forum messages that there are registers that are not detailed in the data sheet.
Is there a set of additional registers that are not published in the datasheet that you can…

Tool/software:
I was looking through SLOA229 ("Working with DC coupled Clock pins in AFE7225") and saw that it was mentioned that the VCM buffer on the chip may not come up if the input signal is not large enough in amplitude to allow…
Brady,
You are correct in that it doesn't specify a max rating for the DAC output directly but it cannot exceed the AVDD3 abs max value which is 3.6V.
It appears that the DAC output is still on with a current draw to hold the output at mid-code.

Part Number: AFE7225 The docs cover DFS_RX and DFS_TX which seem limited to LVDS-only (DFS_TX is in 5.7 - LVDX TX INPUT INTERFACE REGISTERS, and DFS_RX is in 5.8 - LVDS RX OUTPUT INTERFACE REGISTERS).
Is there a CMOS equivalent? The documentation is lacking…

Hi,
As per the current sync DAC requirement, We have given 71.5 ohm pullup to P5V0 and 165 ohm pull-down to ground to maintain 50ohm impedance in AFE DAC output (IOUTP/N_A_DAC and IOUTP/N_B_DAC).
In assembled board, Due to this pullup…
Part Number: AFE7225 For the DAC LVDS signals, that are labeled with non-reused CMOS names in Table 2-2 (why change some but not all?), the pin name's indicated polarity matches with the desription, but the ADC LVDS lines appear to have reversed polarity…
Part Number: AFE7225 Hi,
In recent post I asked if AFE7225 can handle 160MHz signal.
The answer was "if it is instantaneous bandwidth of 160MHz, ii can not"
Here my application is 160MHz is the IQ data(I+, I-, Q+, Q-) coming from RF down converter…
Part Number: AFE7225 Other Parts Discussed in Thread: AFE7700 Hi,
I have baseband TX and RX signals with BW up to 160MHz, can AFE7225 handle them from ADC/DAC bandwidth point of view?
THanks, Tiejun
