Applications
• Small communication module for consumer and industrial applications
• Wearable devices
• Clock for MCU
Description
The FA-128 has been commercialized as a reference clock for communication modules, which
requires high accuracy, and as a clock for wireless communication and microcomputers for applications
that require miniaturization (TWS (True Wireless Stereo), Smart Watch, etc.).
The products created using the element processing technology cultivated over many years contribute
to improving the performance of the customer's system.
