581EN168X2IAT

Oscillators Overview

The 581EN168X2IAT is a Voltage-Controlled Temperature-Compensated Crystal Oscillator (VCTCXO) manufactured by CTS-Frequency Controls. It operates at a nominal frequency of 16.8 MHz and utilizes HCMOS logic output levels. The device is designed for low-power applications, featuring a supply voltage range of 2.5V and a standby mode for power-down functionality. It is housed in an 8-SMD, no-lead surface-mount package with dimensions of 5.0mm x 3.2mm. The oscillator provides high stability, specified at ±0.28 ppm, making it suitable for precision timing requirements in compact electronic designs.

Oscillators Feature Summary

• Integrated voltage control capability for precise frequency tuning within the VCTCXO architecture.
• HCMOS output interface compatible with standard digital logic circuits.
• Dedicated standby mode allows for effective power management during inactive periods.
• Surface-mount construction facilitates automated assembly in space-constrained PCB layouts.

Oscillators Applications

• Precision timing sources for communication equipment requiring stable carrier frequencies.
• Low-power embedded systems where thermal stability and power efficiency are critical.
• Test and measurement instruments needing accurate clock references.
• Wireless modules utilizing 16.8 MHz reference signals.

Oscillators Procurement Notes

Verify the specific ordering suffix to ensure compatibility with required voltage levels and output types. Confirm RoHS compliance status if environmental regulations apply to your manufacturing process. Check datasheet specifications for absolute maximum ratings to prevent damage during operation. Ensure proper handling procedures are followed due to the sensitivity of crystal components to mechanical stress and electrostatic discharge.

Oscillators Selection Notes

Select this component when a stable 16.8 MHz reference is needed with minimal power consumption. The VCTCXO type offers better stability than standard TCXOs across temperature variations. Consider the 8-SMD package size for board space limitations. Verify that the HCMOS output level matches the input requirements of the connected microcontroller or FPGA. Evaluate the need for voltage control input if frequency trimming is required in the final application.
