Hi all,
I would like to confirm the specification of SYNC pin of ADC34J44.
According to the datasheet, the VIH is 1.3V and VIL is 0.5V.
And it seems to be a single end level specification.
However the SYNC input is the differential.
How do I understand this specification?
Is the voltage from o,5V to1.3V the differential input voltage?
If yes,
when I want to use SYNC input as 1.8V CMOS single end,
is it possible following solution?
SYNCM~ is connected to 0.9V as Vcm
SYNCP~ is connected to 1.8V LVCMOS output.
If no, could you please tell me the single input method?
When I looked for the interface conversion IC from 1.8V LVCMOS to 1.8V LVPECL,
I could not find it at TI WEB site.
Regards,
Toshi
