PART NUMBERING GUIDE:
n
The Pletronics part number for an SM7700H series oscillator consists of the following 3 elements:
1.
Overall Frequency Stability over Operating Temperature Range:
SM7745H:
±
50 PPM;
SM7744H:
±
25 PPM
Optional Alphabet Designator for Special Requirement:
SM7745HY: standard specifications;
