ENABLE/DISABLE OPTIONS (E/N)  
CXOXHT oscillators have two enable/disable options, designated E &  
N. The E version has a tristate output and stops oscillating internally  
when the output is placed in a high Z state. The N version does not  
have the control pin, Pin1, connected internally so there is no  
enable/disable function with this option.  
PACKAGING OPTIONS  
CCXOXHT oscillators are available either tray packed <250pcs, or  
tape and reel >250 pieces.  
ENABLE/DISABLE OPTION E - FUNCTION TABLE  
16mm tape, 178mm or 330mm reels (EIA 418).
