7W27000032

Oscillators Overview

The TXC Corporation 7W27000032 is a standard clock oscillator operating at a nominal frequency of 27 MHz. It utilizes CMOS output logic and functions with a supply voltage of 3.3 V. The device features an enable/disable control pin for power management flexibility. It is housed in a compact 4-SMD, No Lead package suitable for surface-mount assembly. The operational temperature range spans from -40°C to +85°C, ensuring reliability in industrial environments.

Oscillators Feature Summary

• Integrates an enable/disable function for active power control
• Provides stable CMOS clock signals via a dedicated output pin
• Operates on a single 3.3 V power supply rail
• Constructed in a small form factor SMD package

Oscillators Applications

• Industrial communication modules requiring precise timing
• Embedded systems needing programmable clock sources
• Consumer electronics utilizing 27 MHz reference frequencies
• IoT devices with low-power standby requirements

Oscillators Procurement Notes

Verify the specific package variant against the manufacturer's datasheet before ordering, as lead frame materials may vary. Confirm that the design supports the required 3.3 V logic levels and current drive capabilities. Ensure the PCB footprint matches the exact dimensions specified for the 4-SMD No Lead configuration to prevent soldering defects during reflow processes.

Oscillators Selection Notes

Select this component when a fixed 27 MHz frequency is mandatory rather than a tunable crystal. The integrated enable pin offers a distinct advantage over passive crystals by allowing direct CPU control of the clock state. This reduces system complexity compared to external gating circuits. Verify that the load capacitance requirements of the host MCU are compatible with the internal oscillator circuitry.

Oscillators Part Context

This part belongs to the TXC standard oscillator family, designed to replace discrete crystal and capacitor networks. It consolidates the resonator, amplifier, and output buffer into a single sealed unit. The 7W series specifically targets applications requiring high stability and low jitter without the need for complex external matching components found in traditional LC oscillator designs.

Oscillators Replacement Considerations

Direct substitutes include other 27 MHz CMOS oscillators in 4-SMD packages such as the Epson SG-8101CB or SiTime SiT9002. When replacing, ensure the new part supports the same 3.3 V supply and has a compatible pinout for the enable signal. Verify that the output swing levels match the input thresholds of the receiving digital logic.
