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
2. Optional Alphabet Designator for Special Requirement:
SM7745HY: standard specifications;
SM7745HE: operating temperature range of -40 to +85°C;
SM7745HS: 45/55% symmetry at 50% of Vcc (CMOS);
SM7745HV: operates at Vcc = 3.3V
(There are other alphabet designators not listed here.)
3. Frequency of Operation in MHz
EXAMPLES: SM7745HV-50.000 MHz; SM7745HE-10.000 MHz; SM7744HY-50.000 MHz
When customer’s requirements are non-standard, a special engineering part number will be assigned.
