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
