XIO2001: Address / data line length

mahiro ueda

Part Number: XIO2001

Hello,

I'm trying to connect XIO2001 and PCI Device IC directly, but I don't know how long the Address / Data line should be.

Is there a regulation regarding the length of the Address / Data line in XIO2001?

Greeting Ueda,

As long as data setup and hold time with respect to clock is within the spec we should be fine.

Thank you for your reply Nasser

Thanks to that, one question was solved.

As an additional question, do all Address / Data lines from 0 to 31 have to be the same length?

I'm sorry for all the amateur questions, but please answer.

The datasheet says:

All synchronous PCI bus signals must be length matched to meet clock setup and hold requirements.

Also see section 9.3.1.
