LVDS RX CHANNELS MAX RATE

Hello, I'm looking for the lowest cost FPGA family from Intel which still have fast enough LVDS RX channels to handle up to 800MHz DDR bus (up to 1.6 Gb/Sec per data RX lane)? Thanx, Eli.

When i look at "Table 34. High-Speed I/O Specifications for Cyclone V Devices" in Cyclone V Device Datasheet at page 47

https://www.intel.com/content/dam/www/programmable/us/en/pdfs/literature/hb/cyclone-v/cv_51002.pdf

The highest clock input frequency for true differential standards is 437.5 which in best case can support data rate up to 875 Mb/Sec in DDR while i'm looking for almost twice that rate.

I see that Arria 10 support up to 1,600 Mb/Sec in DDR mode but these FPGA devices are relatively expensive....
