Occasional ContributorHighspeed LVDS ADC interface to arria 10 fpga
Hi,
I am using high speed ADC (ADS62P25IRGCT) with arria10,
Output of ADC is LVDS, i want single ended input in FPGA,
GPIO ip: is Not suitable as specified in datasheet.
GPIO Intel FPGA IP User Guide: Intel Arria 10 and Intel Cyclone 10 GX Devices
2)LVDS serdes IP:
LVDS SERDES Intel FPGA IP User Guide: Intel Arria 10 and Intel Cyclone 10 GX Devices
The output is parallel and width is multiple of SERDES Factor.
These two may nit suitable for my requirement,
please suggest IP for LVDS to single ended input in FPGA.
Regards,
Rajesh
Yes, you can use it to convert the differential signal to single ended and implement the DDR data capture logic to it. The IP basically configures the IOE element of the device.

ADC is DDR LVDS output,
Please suggest IP which features LVDS and DDR.

The GPIO Intel FPGA IP can be configured to be used with a differential buffer and DDIO as Register mode. You can assign LVDS IO standard to the input pin.

Hi @Ash_R_Intel ,
Thank you for response.
from the GPIO IP Datasheet : "You can use GPIOs in general applications that are not specific to
transceivers, memory interfaces, or LVDS."by the statement given in datasheet,
can we still use GPIO IP for LVDS pins ?
Regards,
Rajesh
