PART NUMBERING GUIDE:
n The Pletronics part number for an ST2200 series oscillator consists of the following 4 elements:
1. Overall Frequency Stability over Operating Temperature Range:
ST2245: ± 50 PPM;
ST2244: ± 25 PPM
2. Optional Alphabet Designator for Special Requirement:
ST2245: standard specifications;
ST2245E: operating temperature range of -40 to +85°C;
ST2245P: 45/55% symmetry at Vcc=1.4V;
(There are other alphabet designators not listed here.)
3. Frequency of Operation in MHz
4. Optional Surface Mount Configuration – SMD
EXAMPLES: ST2245E-10.000 MHz; ST2245P-10.000 MHz, ST2244-10.000 MHz-SMD
n When customer’s requirements are non-standard, a special engineering part number will be assigned.
