F1145HT

TTL TRI-STATE HIGH FREQUENCY CLOCK OSCILLATOR F1100HT The F1100HT Clock Oscillator is designed to drive high frequency TTL applications (up to 10 TTL gates). This part has a tri-state enable/disable function on pin 1 to facilitate testing with automatic test equipment (ATE). • PART NUMBER SELECTION Frequency Stability ±100PPM ±50PPM (to 90 MHz) ±25PPM (to 50 MHz) Part Number F1100HT F1145HT F1144HT FEATURES • High Frequency TTL • Fast Rise/Fall Times • 45/55 Symmetry (1.544 ~ 80 MHz) • Tri-state Enable/Disable • ELECTRICAL CHARACTERISTICS (Ta = 25°C, VDD = 5.0V, RL =400W) OSCILLATORS Frequency Range Frequency Stability Temperature Operating Storage Supply Voltage Input Current PARAMETERS Discontinued (Fo) Note: -40ºC ~ +85ºC "R" version available (ex: F1100HTR) to 90 MHz Actual Size FREQUENCY RANGE 1.544 1.544 1.544 1.544 25.000+ 50.000+ 80.000+ 1.544 80.000+ 1.544 1.544 1.544 1.544 1.544 ~ 110.000 ~ 110.000 ~ ~ ~ ~ ~ ~ ~ ~ 110.000 25.000 50.000 80.000 110.000 80.000 110.000 110.000 CONDITIONS All Conditions* 1.544 -100 -10 -55 +4.5 MIN 110.000 +100 +70 +125 +5.5 16 30 60 75 55 60 5 5 0.4 16 -4 10 10 MAX UNITS MHz PPM ºC V mA (TOPR) (TSTG) (VDD) (IDD) Output Symmetry Rise Time Fall Time Output Voltage Output Current Output Load Start-up Time (TR) (TF) (VOL) (VOH) (IOL) (IOH) (TS) 1.4V Level 0.4V to 2.4V 2.4V to 0.4V IOL = 16 mA IOH = -4 mA VOL = 0.4 V VOH = 2.4 V RL = 400Ω 45 40 % nS V mA TTL mS OUTPUT (Pin 8) ACTIVE ACTIVE High Z ~ 110.000 ~ 110.000 ~ 110.000 ~ 110.000 2.4 * Inclusive of 25ºC tolerance, operating temperature range, input voltage change, load change, aging, shock, and vibration. ***An internal pullup resistor from pin 1 to pin 14 allows active output if pin 1 is left open.
