AOCJY2-10.000MHZ
Overview
The AOCJY2-10.000MHZ is a high-stability Oven Controlled Crystal Oscillator (OCXO) featuring a Voltage Control (VC) function and CMOS output. It provides an exceptionally tight frequency stability of +/-5ppb at a 10.000MHz center frequency, making it suitable for high-precision timing applications where thermal drift must be minimized. The device operates on a 3.3V supply and includes a power-down standby function to manage energy consumption in precision instruments.
Why Choose This Part
The primary advantage is the superior +/-5ppb frequency stability achieved through a sophisticated oven-controlled architecture in a relatively compact 21mm x 21mm 6-DIP package. It also features a voltage control pin for fine-tuning frequency adjustments and a standby mode that reduces power consumption when the precision clock is not actively required.
Applications
Key Specifications
Getting Started
When integrating this OCXO, ensure the PCB layout includes a solid ground plane and thermal relief to prevent localized heating from affecting the internal oven's control loop. Use a low-noise 3.3V LDO regulator to power the device, as supply noise can translate directly into phase jitter. During the initial power-on phase, allow for a warm-up period to reach the specified stability as the internal heater stabilizes the crystal temperature.
