SQ33D Series 3.3 V
CMOS Clock Oscillators
January 2006
• Pletronics’ SQ33D Series is a quartz crystal
controlled precision square wave generator
with a CMOS output.
• The SQ33D series will directly interface TTL
devices also.
• Greatly reduces RFI and EMI system sensitivity
• Minimizes RFI radiation, eases meeting FCC
Class B emissions standards.
• Capable of driving up to 50pF capacitive loads
• Tube packaging is available.

Pletronics may ship the following combinations without notice (this is an enhanced specified device)
44 (25 ppm) stability parts when 45 (50 ppm) was ordered
20 (20 ppm) stability parts when 45 (50 ppm) or 44 (25 ppm) was ordered.
E temperature range parts when extended was not ordered.
S symmetry parts when 40/60% symmetry was ordered.
Pletronics may ship parts that are not marked for extended temperature range but were tested for
extended temperature range, a Certificate of Conformance will accompany these parts.
