SMT Crystal Oscillator - Vic Fraenckel - Jan 17 17:46:00 2005


I have been looking at the specs for both the Epson SG-615and the CMX 309
series SMT crystal oscillators and they both show pin 1 labled OE. However,
the specs do not show how/why it is used. How would I wire that pin (GND or
+5V)? Perhaps I can safely ignore it?

Any enlightenment will be appreciated except, perhaps, from Vasile Surducan
:>{ )

TIA

Vic

OE implies it is active high, and enables the output when tied high. I'd
contact the supplier to make sure.

According to the data sheet
http://www.eea.epson.com/go/Prod_Admin/Categories/EEA/QD/Crystal_Osci
llators/all_oscillators/go/Resources/TestC2/SG615PCN tie OE high or
leave open to enable the output.
