Input Current (Icc) & Rise & Fall Time (Tr & Tf) & Jitter Logic "1" & Logic "0" (See next page) Output Load Tri-state Output Packaging (see page R1, Figure 4) 1.500 MHz - 69.999 MHz (Consult factory for specific available frequencies) 50 PPM is standard, but 25 PPM is also available for certain frequencies. 0 - 70C is standard, but can be extended to -40 to +85C for certain frequencies 1.500 MHz - 30.000 MHz 30.001 MHz - 69.999 MHz SM7700HY SM7700HY SM7700HV 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. 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". 16 mm tape, 178 mm, 254 mm or 330 mm reel: 1000 parts per reel. For quantities <250: 100 parts per tray PART NUMBERING GUIDE: n 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 Optional Alphabet Designator for Special Requirement: SM7745HY: standard specifications; SM7745HE: operating temperature range of -40 to +85C; SM7745HS: 45/55% symmetry at 50% of Vcc (CMOS); SM7745HV: operates at Vcc = 3.3V (only needed for over 30.000MHz) (There are other alphabet designators not listed here.) Frequency of Operation in MHz 2. 3. EXAMPLES: SM7745HV-50.000 MHz; SM7745HE-10.000 MHz; SM7744HY-50.000 MHz n When customer's requirements are non-standard, a special engineering part number will be assigned.
