PART NUMBERING GUIDE:
n The Pletronics part number for a PLLC series oscillator consists of the following 4 elements:
1. Model Number Series:
SM1145PL: Leadless Surface Mount;
P1145-PL: Full Size Metal Thru-Hole;
SQ3345PL: Half Size Metal Thru-Hole
2. Overall Frequency Stability over Operating Temperature Range:
SM1145PL: ± 50 PPM;
SM1144PL: ± 25 PPM
3. Optional Alphabet Designator for Special Requirement:
SM1145PL: standard specifications;
SM1145PLE: operating temperature range of -40 to +85°C;
SM1145PLV: operates at Vcc = 3.3V
(There are other alphabet designators not listed here.)
4. Frequency of Operation in MHz
EXAMPLES: P1145-PL-125.000 MHz, SM1145PLE-150.000 MHz, SQ3344PLV-72.000 MHz
n When customer’s requirements are non-standard, a special engineering part number will be assigned.
