The F4500 offers an input voltage of 1.8 V ± 5%, with an operating voltage as low as 1.6 V. The F4500 Series also provides greater efficiency both in system design and in the operation of the oscillator. Greater system efficiency is achieved through the oscillator's direct connection to the system's processor, which eliminates the extra circuitry previously needed to match the processor's voltage to the oscillator's voltage.

The F4500 Series is ideal for low current, battery-operated applications including wireless LANs, handheld computers, and other portable applications. Frequency range is 30 to 70 MHz and the maximum input current is 15 mA. Stabilities for the F4500 Series are 25 ppm, 50 ppm, and 100 ppm at both the – 10°C to 70°C and – 40°C to 85°C temperature range. It is housed in a 5 × 7.5 mm package.
