How to tell if a product is a TCXO or a VCTCXO from the datasheet

2025-04-25

How to tell if a product is a TCXO or a VCTCXO from the datasheet

 

Both Temperature Compensated Crystal Oscillators (TCXOs) and Voltage-Controlled Temperature Compensated Crystal Oscillators (VC-TCXOs) are designed to combat frequency variations caused by temperature changes. They employ temperature compensation techniques to maintain a stable output frequency across a defined temperature range. This makes them a preferred choice over other crystal oscillator types.

TCXOs and VC-TCXOs find use in a variety of applications, including:

  • Base Stations
  • GPS/GNSS Receivers
  • Industrial Instrumentation
  • Wireless Systems
  • Test and Measurement Instruments

1. Firstly,let's see the pads functions.

 

A: If the pad 1 is VC, then it is VCTCXO

B: If the pad 1 is GND, means the pad is not connect, then it is normal TCXO, no voltage control functions.

2. See the specs difference, below specs is only for VCTCXO, and There is no same specs in TCXO

 

Frequency Control Range

Also, there are some other difference in TCXO and VCTCXO like below table.

latest company news about How to tell if a product is a TCXO or a VCTCXO from the datasheet 2

 

 

In conclusion, the decision between TCXO and VC-TCXO hinges on the specific needs of the application, taking into account the necessity for frequency adjustment, temperature stability requirements, and budgetary constraints.
