7CL-27.120MBD-T

Oscillators Overview

The TXC CORPORATION 7CL-27.120MBD-T is a standard CMOS quartz oscillator operating at 27.12 MHz. It features a supply voltage of 3.3 V and includes an enable/disable control function. The device offers tight frequency stability of ±25 ppm across an extended industrial temperature range of -40°C to +85°C. Housed in a compact 4-SMD, no-lead package with dimensions of 5.0 mm x 3.2 mm, it is designed for surface-mount assembly. This component serves as a precise clock source for digital circuits requiring stable timing signals.

• Operates on a single 3.3 V power supply
• Includes hardware enable and disable control functionality
• Supports wide industrial temperature operation from -40°C to +85°C

Oscillators Applications

• Embedded system clock generation
• Microcontroller timing sources
• Communication interface synchronization
• Digital logic circuit timing references

Oscillators Procurement Notes

Verify the specific suffix 'BD' confirms the 3.3V CMOS output and enable/disable feature. Ensure the design accommodates the 5.0x3.2mm footprint. Confirm thermal requirements align with the -40°C to +85°C operational range. Check for RoHS compliance status if required by project specifications. Validate supply voltage compatibility with the target circuitry before integration.

Oscillators Selection Notes

Select this model when a fixed-frequency CMOS clock source is needed with enable control. It is suitable for designs requiring ±25 ppm stability over wide temperatures. Compare against basic crystals if programmability is not required. Consider pin-out compatibility with existing PCB layouts. Evaluate power consumption constraints relative to other oscillator types.

Oscillators Part Context

This part belongs to the 7CL series of standard clock oscillators from TXC Corporation. The series provides various frequencies and packages. The 7CL variant specifically targets applications needing reliable timing with low jitter and robust environmental tolerance. It complements the company's broader portfolio of resonators and crystals.

Oscillators Replacement Considerations

Public confirmed substitute: QT325G-27.120MAHV-T (QST). Verify electrical parameters match 3.3V operation and ±25 ppm stability. Check package dimension compatibility (5.0x3.2mm vs 3.2x2.5mm). Ensure pin configuration alignment for direct replacement.
