1MHz - 30MHz Variable Oscillator
Emulation Technology offers the VROSDIP4.301030 1MHz to 30MHz variable oscillator in a half-can DIP footprint. This high-quality variable oscillator allows the engineer to easily fine-tune the required reference frequency for system development or debug. A single potentiometer is used to adjust the output frequency from 1MHz to 30MHz. An Output Enable pin allows the oscillator's HCMOS outputs to be in high-impedance or normal operation. The VROSDIP4.301030 is constructed on a compact two-layer FR4 PCB.
Features & Benefits
- Provides a variable oscillator in a half-can footprint
- Allows the system designer to efficiently develop and debug the system without the need to specify a particular fixed oscillator
- HCMOS output with high-impedance state
- Output Enable pin can be left unconnected for normal operation or held LOW for high-impedance output
- Wide frequency, power supply and operating temperature ranges
- Low frequency drift over time, temperature and power supply
- Simple frequency adjustment through a single potentiometer
- Frequency adjustment tool included: see TOOL-POT-ADJ
- Ideal for lab environments
