PART NUMBERING GUIDE:
n
n The Pletronics part number for an SM1100C series oscillator consists of the following 3 elements:
1.
Overall Frequency Stability over Operating Temperature Range:
SM1145C:
± 50 PPM;
SM1144C:
± 25 PPM
2.
Optional Alphabet Designator for Special Requirement:
SM1100CY: standard specifications;
SM1145CE: operating temperature range of -40 to +85
°C;
SM1100CS: 45/55% symmetry at 50% of Vcc;
SM1100CV: operates at Vcc = 3.3V (only needed for over 30.000MHz)
(There are other alphabet designators not listed here.)
3.
Frequency of Operation in MHz
EXAMPLES: SM1145CV-50.000 MHz; SM1145CS-10.000 MHz; SM1144CE-50.000 MHz
