EMEM8004 parts incorporate an all-silicon resonator that is robust and perfoms well in high shock and vibration environments. EMEM8004 oscillators are available in four, industry-standard smd packages: 7 x 5mm, 5 x 3.2mm, 3.2 x 2.5mm and 2.5 x 2.0mm. the part may be 'dropped in' to most pcb footprints as standard crystal oscillators. the EMEM8004 oscillators have the same functionality as emem8001 parts but with a greater output drive (c l = 40pf) the programmable EMEM8004 series are available on very short leadtimes. electrical specifications features frequency range 1.0mhz to 150mhz frequency stability 20, 25 or 50ppm operating voltage: 1.71v to 3.60v operating temperature range ext. commercial: -20 to +70c industrial: -40 to +85c ext. industrial: -40 to +105c operating and standby current 8ma operating (40mhz) 15a standby ultra-miniature footprint 2.5 x 2.0 x 0.85mm 3.2 x 2.5 x 0.85mm 5.0 x 3.2 x 0.85mm 7.0 x 5.0 x 0.85mm excellent shock & vibration resistance pb free, rohs, reach svhc compliant iso9001 (2008) qualified page 1 of 5 parameter symbol condition min. typ. max. unit frequency f 0 single frequency 1 150 mhz frequency tolerance ?f includes frequency variations due to initial tolerance, temperature and power supply voltage. 10, 25 & 50 ppm ageing ?f 1 year @ 25 5 ppm supply current, standby i dd t = 25c 15 a output startup time 2 t su t = 25c 1.0 1.3 ms output disable time t da 20 100 ns output duty cycle sym 45 55 % input logic levels input logic high input logic low v ih v il 0.75*v dd 0.25*v dd volts 1. absolute maximum ratings are those values beyond which the safety of the device cannot be guaranteed. the device should not be operated beyond these limits. 2. output frequency to within 100ppm of final stable output frequency. 3. see typical cycle to cycle jitter graph for frequency dependence. programmable low power precision cmos EMEM8004 - mems oscillator 1.0mhz to 150.0mhz
