FO7HSBEM33.0-T1

Oscillators Overview

The Fox Electronics FO7HSBEM33.0-T1 is a standard surface-mount HCMOS oscillator housed in a 7mm x 5mm package. It operates at a nominal frequency of 33MHz with a stability of ±20ppm. The device supports a supply voltage of 3.3V (±5%) and functions within an industrial temperature range of -40°C to +85°C. Key electrical characteristics include a typical operating current of 7mA, a rise/fall time of ≤5ns, and a duty cycle of 45% to 55%. The output swing ranges from 10% to 90% of Vdd.

Oscillators Feature Summary

• Provides stable timing signals via HCMOS output compatible with digital logic circuits
• Features low power consumption suitable for battery-powered or energy-efficient designs
• Includes an enable pin with internal pull-up resistor for simplified board layout

Oscillators Applications

• Industrial edge gateway hardware design
• PHY clock source generation
• Microcontroller main clock sourcing
• High-speed ADC timing applications

Oscillators Procurement Notes

Verify the specific suffix against official documentation to confirm voltage tolerance and stability ratings. Ensure the ordering part number matches the required operational parameters before procurement. Cross-reference datasheets for exact electrical limits to prevent integration errors.

Oscillators Selection Notes

Select this component for designs requiring a 3.3V supply with ±5% tolerance and ±20ppm stability. It serves as a direct replacement for older F4 series oscillators without PCB modifications. Consider the 7mA current draw for power budgeting and verify the 5ns transition times meet interface requirements.

Oscillators Part Context

This model belongs to the FO7HS series, which replaces legacy F4100/F4400/F4500 lines. It maintains the industry-standard 7x5mm footprint while offering improved parameter flexibility across multiple voltage options. The series targets robust industrial applications requiring reliable clock generation.

Oscillators Replacement Considerations

Directly replaces Fox F4100, F4400, and F4500 series components. No PCB layout changes are required due to identical 7x5mm packaging dimensions. Verify that the target application supports the specific 3.3V supply and HCMOS output levels.

Oscillators FAQ

What is the default state of the enable pin?

The enable pin has an internal pull-up resistor to VDD. When left unconnected, the output is active by default.

How does the device behave when the enable pin is pulled low?

Pulling the enable pin below 30% of Vdd places the device into a high-impedance state.
