Electrical Characteristics

The F4100 has a frequency range from 1.000 MHz to 156.250 MHz, encompassing multiple versions for various application needs. It ensures frequency stability over all conditions within ±100 parts per million (PPM) and offers operating temperature ranges of -10°C to +70°C for standard (‘R’ version) and an extended range of -40°C to +85°C for specific models. The device’s storage temperature can span from -55°C to +125°C.

Regarding power specifications, the supply voltage (VDD) can range from +2.97V to +3.63V. Input current (IDD) varies with frequency and can reach up to 40 mA for the highest frequency. The oscillator maintains output symmetry between 45% and 55% up to 50.000 MHz and 40% at higher frequencies. Additionally, rise and fall times are kept to a minimum, ranging from 2.97V to 0.33V. The output voltage levels are 0.33V for VoL and 2.97V for VOH under the specified loading conditions, with output current capabilities of up to mA for both high and low output levels.

Other electrical parameters include a standby current of 5μA when VIL is less than 0.99V, which significantly reduces power consumption when the device is not in active mode. Moreover, the oscillator provides fast start-up and enable/disable times, with 10ms typically quoted for output enable timing.

Additional Features and Recommendations

An internal pull-up resistor allows for active output if the enable/disable pin is left open, enhancing the flexibility of the device’s use in circuit design. A 0.01μF bypass capacitor is recommended between VDD and GND to minimize power supply line noise. The output pin is actively driven to provide a reliable clock signal.

Model numbers are configured based on operational levels, frequency ranges, operating temperatures, and stability requirements, with codes to specify each of these parameters. Detailed solder pad layouts and dimensions are provided, ensuring compatibility with standard SMD manufacturing processes.
