| Stratum IV CB3 & CB3LV HCMOS/TTL CLOCK OSCILLATOR FEATURES * * * * * * * * * Standard 7.5x5.0mm Surface Mount Footprint HCMOS/TTL Compatible Fundamental and 3rd Overtone Crystals Frequency Range 1.5 - 80 MHz Frequency Stability, 32 ppm for 20 Years +3.3Vdc or +5.0Vdc Operation Operating Temperature to -40C to +85C Output Enable Standard Tape & Reel Packaging * RoHS/Green Compliant DESCRIPTION The CB3/CB3LV is a ceramic packaged Clock oscillator offering reduced size and enhanced stability. The small size means it is perfect for any application. The enhanced stability means it is the perfect choice for today's communications applications that require tight frequency control. ORDERING INFORMATION CB3 SUPPLY VOLTAGE LV = +3.3Vdc Blank = +5.0Vdc FREQUENCY STABILITY S4 = 32 ppm OPERATING TEMPERATURE RANGE C = -20C to +70C (standard) I = -40C to +85C - - M FREQUENCY IN MHz M - indicates MHz and decimal point. Frequency is recorded with minimum 4 significant digits to the right of the "M". Example Part Number: CB3LV-S4-32M7680 or CB3-S4-32M7680 Document No. 008-0257-0 Page 1 - 4 Rev.
