PART NUMBERING GUIDE:
n The Pletronics part number for an SM1100B series oscillator consists of the following 3 elements:
1. Overall Frequency Stability over Operating Temperature Range:
SM1145B: ± 50 PPM;
SM1144B: ± 25 PPM
2. Optional Alphabet Designator for Special Requirement:
SM1145BY: standard specifications;
SM1145BE: operating temperature range of -40 to +85°C;
SM1145BS: 45/55% symmetry at 50% of Vcc;
SM1145BV: operates at Vcc = 3.3V
(There are other alphabet designators not listed here.)
3. Frequency of Operation in kHz or MHz
EXAMPLES: SM1145BV-50.000 MHz, SM1145BE-25.000 MHz, SM1144BY-50.000 MHz
n When customer’s requirements are non-standard, a special engineering part number will be assigned.
