DOT050V-010.0M
Overview
The DOT050V-010.0M is a high-precision 10 MHz Voltage Controlled Temperature Compensated Crystal Oscillator (VCTCXO) designed for applications requiring exceptional frequency stability. It operates at 3.3V and provides an LVCMOS output with a remarkably low frequency stability of +/-50ppb over a 0 to 70 degrees Celsius range. This surface-mount component is ideal for timing and synchronization tasks where standard TCXOs cannot meet the tight drift requirements.
Why Choose This Part
The primary advantage of this part is its +/-50ppb stability, which is significantly better than standard +/-2.5ppm TCXOs, reducing the need for frequent calibration. Its small 6-SMD footprint and low 10mA maximum current draw allow for high-performance timing in space-constrained, low-power designs. The voltage control (VC) function enables fine-tuning of the output frequency to compensate for aging or to phase-lock to an external reference.
Applications
Key Specifications
Getting Started
When integrating this VCTCXO, ensure a clean 3.3V supply with local decoupling capacitors to minimize phase noise. The control voltage pin should be driven by a low-noise DAC or a filtered PWM signal if frequency adjustment is required; otherwise, refer to the datasheet for the appropriate bias voltage for nominal 10 MHz operation. Lay out the LVCMOS output trace with controlled impedance and minimal length to preserve signal integrity and reduce EMI.
