AFE5818: AFE5818 register configurations

Akshay Yadur

Prodigy 80 points

Part Number: AFE5818
Other Parts Discussed in Thread: AFE5812,

Tool/software:

We used AFE5812 for one project and are using AFE5818 for another. Are the register configurations the same for both devices, and what other differences should we be aware of?

Hi,

Both register configuration are different as it is not same core .Mainly ADC part of it is fully changed .

Thank you for the reply,

Could you share any reference which could help us in development for RTL

Do you have EVM and gui for that ? By configuring EVM you can get basic settings of device .

What exactly you are looking for ? If you have any specific queries I can help on that

We don't have a EVM, as shared earlier for review, we have a FPGA and a ADC interface ,wanted to know how we can configure ADC using FPGA, Like what all registers are required to configure for ADC to start functioning, if u have any reference it would be great

Also want to just confirm that any kind of configurations which need to be done are possible through ADCs SPI communication right!?

Are there any tools available for configuring ADC registers to generate a coefficient file?

0 Sachin H K 5 months ago in reply to Sachin H K

Below writes are enough to bringup ADC in 14bit mode

DIE | Register Addr Data #description

VCA|0xC3 0x0000 #PGA_GAIN 00 = 24dB
VCA|0XC4 0x0000 #LNA_GAIN_GBL 00 = 18dB
ADC|0x03 0x2012 # DEMOD_RES = 001 for 14-bit # SER_DATA_RATE = 001 for 14x # EN_DEMOD = 0
ADC|0x04 0x0001 # ADC_RES = 01 for 14 bit
ADC|0x01 0x0014 # Mandatory Bits

Thank you for the reply

but what are the tools for configuring this and generating coefficient files

0 Sachin H K 5 months ago in reply to Akshay Yadur

This is not by any tool .. For generating filter Coefficient you can refer to the attached script.
