SM7700D SERIES nn CMOS COMPATIBLE WITH TRI STATE OUTPUT nn LEADLESS SURFACE MOUNT OSCILLATOR IN 7 x 5mm CERAMIC PACKAGE nn 3RD OVERTONE CRYSTAL USED nn LOW JITTER (SEE TABLE NEXT PAGE) STANDARD SPECIFICATIONS:STANDARD SPECIFICATIONS: 70.000 MHz 160.000 MHz Frequency Range (Consult factory for specific available frequencies) Frequency Stability over Operating 50 PPM is standard, but 25 PPM is also available. Temperature Range 0 - 70C is standard, but can be extended to -40 to +85C for Operating Temperature Range certain frequencies. Input Voltage (Vcc) 5 Volt 10% is standard, but 3.3 Volt or 2.5 Volt 10% also available. Symmetry (Duty Cycle) 40/60 - 60/40% is standard, but 45/55% symmetry at 50% of Vcc is (See next page for definition.) also available. Input Current (Icc) & Rise and Fall Time Depends on frequency and output load. See next page. (Tr & Tf) & Jitter Logic 1 & Logic 0 (see next page) 90% of Vcc MIN. 10% of Vcc MAX. Output Load Can drive up to 15pF Normal output when pin 1 is open (no connection) Tri-state Output Normal output when pin 1 is at logic 1 High-Impedance Output when pin 1 is at logic 0. 16 mm tape, 254 mm reel: 1000 parts per reel. Packaging (see page R1, Figure 4) For quantities <250: 100 parts per tray. PART NUMBERINPART NUMBERING GUIDE:G GUIDE: nn The Pletronics part number for an SM7700D series oscillator consists of the following 3 elements: 1. Overall Frequency Stability over Operating Temperature Range: SM7745D: 50 PPM SM7744D: 25 PPM 2. Optional Alphabet Designator for Special Requirement: SM7745DY: standard specifications SM7745DE: operating temperature range of -40 to +85C SM7745DS: 45/55% symmetry at 50% of Vcc SM7745DV: Operates at Vcc = 3.3 V SM7745DW: Operates at Vcc = 2.5 V (There are other alphabet designators not listed here.) 3. Frequency of Operation in MHz EXAMPLES: SM7745DSV-106.250 MHz SM7745DW-125.000 MHz SM7744DY-100.000 MHz nn When customers requirements are non-standard, a special engineering part number will be assigned.
