FO7HSKBM38.4-T2

Oscillators Overview

The Fox Electronics FO7HSKBM38.4-T2 is a surface-mount HCMOS crystal oscillator operating at 38.4 MHz. It utilizes the standard 7050 (7mm x 5mm) package with a 4-SMD, no-lead footprint. The device supports a 1.8V supply voltage with ±5% tolerance and features an enable/disable function via pin 1. Frequency stability is rated at ±50 ppm across an industrial temperature range of -40°C to +85°C. Typical supply current is 15 mA at this frequency, with a standby current of 10 μA. Output swing ranges from 20% to 80% of Vdd, and rise/fall times are approximately 3 ns.

Oscillators Feature Summary

• Integrated enable control with internal pull-up resistor for simplified PCB layout
• Standard 7050 SMD footprint enabling direct replacement in existing designs
• HCMOS output compatible with standard digital logic inputs

Oscillators Applications

• Industrial edge gateway hardware design
• PHY clock source selection for network interfaces
• Low-power battery-supplied high-speed equipment

Oscillators Procurement Notes

Verify component status as the FO7HS series has been subject to production change notices. Confirm specific supply voltage tolerance and frequency stability requirements against datasheet specifications before ordering. Ensure compatibility with existing 1.8V power rails and check for any end-of-life notifications from the manufacturer or authorized distributors.

Oscillators Selection Notes

Select this model for applications requiring a 38.4 MHz clock in a compact 7050 package. The 1.8V variant offers lower power consumption compared to higher voltage options, making it suitable for energy-constrained systems. Verify that the ±50 ppm stability meets system timing requirements and confirm the enable pin logic aligns with the host controller's idle state preferences.

Oscillators Part Context

This component belongs to the Fox Electronics O7HS series of surface-mount oscillators. It serves as an upgrade path for older F4 series parts, offering improved parameters while maintaining the same physical dimensions. The series is designed for industrial and consumer electronics requiring reliable clock signals in space-constrained environments.

Oscillators Replacement Considerations

The FO7HS series is documented as a direct replacement for the older Fox F4100, F4400, and F4500 series components without requiring PCB layout changes due to identical 7050 packaging.
