HIGH-FREQUENCY CRYSTAL OSCILLATOR
SG-636 series
Product number (please refer to page 1)
Q33 6 3 6 x x x x x x x 0 0
• A small SMD that enables high-density mounting.
• A general-purpose device with builtin heat-resisting cylindrical AT-cut
crystal and allowing almost the same temperature condition for soldering
as SMD IC.
• Low current consumption by output enable function(OE) or standby
function(ST).
