PART NUMBERING GUIDE:
nn The Pletronics part number for an SM1100C series oscillator consists of the following 3 elements:
1. Overall Frequency Stability over Operating Temperature Range:
SM1145C: ± 50 PPM;
SM1144C: ± 25 PPM
± 50 PPM is standard, but ± 25 PPM is also available for certain frequencies.
0 - 70°C is standard, but can be extended to −40 to +85°C for
certain frequencies
1.000 MHz – 30.000 MHz 30.001 MHz – 50.000 MHz
SM1100CY SM1100CY SM1100CV
5 Volt ± 10% or 3.3 Volt ± 10% 5 Volt ± 10% only 3.3 Volt ± 10% only
40/60 - 60/40% is standard, but 45/55% symmetry at 50% of Vcc
is also available.
Depends on frequency and output load. See next page.
Normal output when pin #1 is open (no connection);
Normal output when pin #1 is at logic “1”;
High-Impedance Output when pin #1 is at logic “0”.
24 mm tape, 330 mm reel: 1000 parts per reel.
For quantities <250: 23 parts per tube.
2. Optional Alphabet Designator for Special Requirement:
SM1100CY: standard specifications;
SM1145CE: operating temperature range of -40 to +85°C;
SM1100CS: 45/55% symmetry at 50% of Vcc;
SM1100CV: operates at Vcc = 3.3V (only needed for over 30.000MHz)
(There are other alphabet designators not listed here.)
3. Frequency of Operation in MHz
EXAMPLES: SM1145CV -50.000 MHz; SM1145CS-10.000 MHz; SM1144CE-50.000 MHz
nn When customer’s requirements are non-standard, a special engineering part number will be assigned.
