Max 10 - Difference in performance between low-speed and high-speed I/O pins

--- Quote Start ---

Hi,

there does not seem to be any information in the Max 10 user guide, but in the datasheet. Please note that those are two different documents :-) older devices, e.g. Cyclone II, combined those two documents in a single PDF, but Altera seems to split their documents into a handbook/uiserguide and a datasheet lately.

The datasheet (https://documentation.altera.com/#/link/mcn1397700832153/mcn1397643748870 (https://documentation.altera.com/#/link/mcn1397700832153/mcn1397643748870)) says hat the low-speed pins support data rates up to 300 Mbps, whereas the high-speed pins support up to 310 Mbps (please double-check against your specific requirements, as the datasheet is in fact a bit more complicated, depending on the I/O standard you use).

Best regards,

Sorry for necro, but saw an inaccurate post that needed correcting. :nerd:

I am trying to determine specifications for my client who will be using the MAX 10 in a prototype board. My research found no specification on low-speed I/O capability from Intel/Altera.

According to that datasheet linked by GooGooCluster it speaks ONLY to the HIGH-SPEED I/O pins as up to 300Mbps (LVDS/PPDS/RSDS)...and only in terms of transmitting (output)... very odd. There is not a word on specific I/O data/clock rate limits for low-speed pins (bank1/8). Just looking at the datasheet, if the high-speed is limited to 300 MHz, one can only assume that the low-speed would be less than that. IMO 150 Mbps/MHz is a reasonable limit for low-speed if high-speed is 300.

Being that it's been over 2 years since OP posted, I would estimate they were successful in their application.

If anyone has any benchmark data for the Max10 low-speed pins (ideally 10M08 but any 10MXX should give me an indication of limits) and is willing to share, they would be showered with appreciation for contributing here. Please and thank you.
