16MHz 16.000M HC-49S Passive Crystal Oscillator

• Load Capacitance: ±20 PPM
• Color: Silver
• Dimensions: 16 x 10.5 x 4.5 mm

Features:

• Type: Passive Crystal
• Terminals: 2 (non-polar element)
• Oscillation: Requires an external clock circuit to generate oscillation; does not oscillate on its own.

Passive crystals, like this one, need the help of an on-chip DSP oscillator and can operate across various voltage levels. This makes them versatile for different clock signal voltage requirements in DSP systems. While passive crystals are generally more affordable and ideal for large-scale production, their signal quality can be weaker, and the peripheral circuit may need capacitors, inductors, and resistors for signal enhancement. Additionally, changing the frequency of the crystal requires adjusting the peripheral circuit configuration.

For applications requiring higher precision, it's recommended to use a high-accuracy quartz crystal rather than lower-precision ceramic alternatives.
