521T20025CTR

Oscillators Overview

The CTS-Frequency Controls 521T20025CTR is a Temperature Compensated Crystal Oscillator (TCXO) operating at 20 MHz. It utilizes HCMOS output logic and functions on a 2.8V supply voltage. The device features an enable/disable control function and is housed in a compact 4-SMD, No Lead package with dimensions of 3.2mm x 2.5mm. Designed for surface mount installation, it supports applications requiring stable frequency generation under varying thermal conditions.

Oscillators Feature Summary

• Temperature compensation ensures frequency stability across operational temperature ranges.
• Integrated enable/disable functionality allows for power management control.

Oscillators Applications

• Telecommunications equipment requiring precise clock signals
• Portable electronic devices utilizing low-voltage digital circuits
• Industrial systems needing reliable timing sources

Oscillators Procurement Notes

Verify the specific supply voltage requirement of 2.8V against target circuit designs to ensure compatibility. Confirm that the HCMOS output logic levels align with downstream component inputs. Ensure the 4-SMD footprint matches the PCB layout constraints. Check for RoHS compliance status if environmental regulations apply to the final assembly.

Oscillators Selection Notes

Select this model when a 20 MHz reference signal is required with temperature-induced drift correction. The 2.8V operation suits modern low-power digital interfaces better than higher voltage alternatives. Consider the enable pin utility for system-wide power savings during idle states compared to always-on oscillators.

Oscillators Part Context

This component belongs to the 521 series of TCXOs from CTS-Frequency Controls. It shares the same fundamental form factor and enable capabilities as other models in the line, such as the 521M24020CTR, but differs in operating voltage and specific frequency tuning characteristics tailored for 20 MHz applications.

Oscillators Replacement Considerations

Direct substitutes within the same series may include variants with different frequencies or voltages, such as the 521M24020CTR, provided the electrical parameters match the design requirements. Cross-referencing datasheets is essential to verify pinout and voltage compatibility before substitution.
