356P270B3C3T

Oscillators Overview

The CTS-Frequency Controls 356P270B3C3T is a Voltage-Controlled Crystal Oscillator (VCXO) operating at a frequency of 27 MHz. It utilizes an LVPECL output type and requires a 3.3V supply voltage. The device features enable/disable functionality, with a maximum supply current of 88mA during operation and 22mA in the disabled state. It offers a frequency stability of ±50ppm and an absolute pull range of ±50ppm. The component is housed in a 6-SMD, no-lead package measuring 7.00mm x 5.00mm x 1.85mm.

Oscillators Feature Summary

• Supports voltage-controlled frequency adjustment via absolute pull range
• Provides low-voltage positive emitter-coupled logic (LVPECL) differential outputs
• Includes hardware enable and disable control for power management

Oscillators Applications

• Telecommunications equipment requiring precise clock synchronization
• Data communication systems utilizing high-speed serial interfaces
• Test and measurement instruments needing stable frequency references

Oscillators Procurement Notes

Verify the specific ordering suffix to ensure compatibility with required output types and supply voltages. Confirm that the selected variant matches the necessary frequency stability and pull range specifications for the target application environment. Check for RoHS compliance status if environmental regulations apply to the manufacturing process.

Oscillators Selection Notes

Select this model when LVPECL outputs are required for noise immunity in high-speed digital circuits. Ensure the design accommodates the 3.3V supply requirement and the thermal characteristics of the surface-mount package. Consider the enable pin functionality if dynamic power saving is a system priority.
