Product Introduction:OCETHCJTNF-100.00000 Product Introduction

The OCETHCJTNF-100.00000 from Taitien is a 100 MHz standard crystal oscillator (XO) providing CMOS output from a 1.8V supply. The device uses a crystal-based resonator for low phase noise and excellent frequency stability of ±100ppm over the -20°C to +70°C operating range. The Enable/Disable function allows system-level power management, reducing supply current to 10µA maximum when disabled. The OC series uses a 4-SMD no-lead package measuring 7.0 x 5.0 x 1.5mm, compatible with standard surface-mount assembly processes. The H in the part number denotes the 1.8V supply voltage variant, C denotes CMOS output, J denotes the temperature stability grade, and NF denotes the Enable/Disable function. The device is RoHS3 compliant with MSL 1 rating.

Working Principle:OCETHCJTNF-100.00000 Working Principle

The OCETHCJTNF-100.00000 operates through three key subsystems:

1. Crystal Resonator: An AT-cut quartz crystal provides the frequency reference at 100 MHz. The crystal operates in fundamental or overtone mode, depending on the frequency. The piezoelectric property of quartz converts electrical energy to mechanical vibration at the resonant frequency, providing high Q (>10,000) and excellent frequency stability.

2. Oscillator Circuit: An integrated sustaining amplifier maintains oscillation by compensating for crystal losses. The amplifier provides the gain and phase shift required to satisfy the Barkhausen criterion. For 100 MHz operation, the circuit typically uses a Colpitts or Butler oscillator topology with the crystal in the feedback path. A limiter circuit stabilizes the oscillation amplitude.

3. CMOS Output Buffer: The oscillator signal is buffered through a CMOS output driver that provides rail-to-rail output swing at the 1.8V supply. The output buffer isolates the crystal oscillator from load variations and provides sufficient drive current (typically 16mA) for clock distribution. The Enable/Disable function gates the output buffer, reducing supply current to 10µA when disabled.
