Depends on frequency and output load. See next page. 90% of Vcc MIN.; 10% of Vcc MAX. 15 pF is standard. Contact factory for heavier loads. 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. PART NUMBERING GUIDE: n 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 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 n When customer’s requirements are non-standard, a special engineering part number will be assigned.
