4.8. IC Reference Clock Interface

4.8.1.

Features

TC35679 has the following features for IC reference clock interface.



Clock frequency: 26 MHz (please adjust the accuracy to < 50 ppm at the temperature in use)

TC35679 doesn’t require external feedback resistors and load capacitor because it has an internal feedback resistor and capacitor

array between XOIN and XOOUT. Please adjust capacitor array based on PCB layout and assembly if necessary within the range

of the crystal’s specification.
