Hi friends ,
I'am designing a controller board which works at 1.8 V / 2.5 V.
However , most of the interfaces connected to it like SDIO ,
Pcie , PCI , memories & plenty of other stuff on the board operates
at 3.3 V.
I have about 200 or more signals where a level conversion is
required from 1.8V to 3.3V & Vice Versa .I'am planning to use
a bi-directional level shifter for this purpose with ideally zero delay.
Else , with delay's as low as possible.
Can anyone suggest. a good bidirectional level shifter ( 1.8V <--> 3.3V)
with minimum pipe line delay's .Since i have large no of signals which
require level conversion , it is preferable to use IC's with as many no of
pin connections as possible ( Idea is to reduce the BOM count - not the
price ).
The key is bi directional & Auto sensing with lowest delay's possible.
Thanks in Advance !!
Regards
Sunil.
