Re: XAUI AC coupling
Ladies and Gentlemen,
A recap of which way folks are leaning on this issue:
Allow AC or DC-coupling
Ed Grivna - Cypress
Dawson Kesling - Intel
Jeff Porter - Motorola
Rich Taborek - nSerial
Simon Sabato - Intel
Tom Palkert - AMCC
Sharam Hakimi - Lucent
Fred Weniger - Vitesse
Mandatory AC-coupling
Vipul Bhatt - Finisar
Larry Miller - Nortel
Joel Dedrick - PMC-Sierra
Richard Dugan - Agilent
Justin Chang - Quake
Ali Ghiasi - Newport Communications
Chris Simoneaux - Picolight
Pat Thaler - Agilent
Geoff Thompson - Nortel
Howard Frazier - Cisco
Clearly there's no clear direction. However, as a compromise, I'm not
averse to going in the following direction: Specify and mandate
AC-coupled operation for XAUI. An note accompanying the coupling text
should allow DC-coupled operation in XAUI links which meet all other
XAUI specifications. Furthermore the overview and application subclauses
must be modified to show cause for AC-coupling is required. The current
test strongly suggests that DC-coupling is more appropriate (i.e.
chip-to-chip interconnect). What say?
