Resonators - (165 companies)Resonators are frequency-selective electronic circuits that can produce a fixed (resonant) frequency when properly excited. The value of the resonant frequency depends on the circuit 's components (e.g., inductors, resistors, capacitors, crystals, etc.). Search by Specification | Learn More -
Crystals - (421 companies)Crystals are naturally occurring materials that can be induced to resonate (vibrate) at an exact frequency. Quartz, a piezoelectric crystal that provides excellent mechanical and electrical stability, acquires a charge when compressed, twisted, or distorted. Search by Specification | Learn More -
IC Timers - (73 companies)IC timers are semiconductor circuits that generate or set timing for electronic circuits. Search by Specification | Learn More -

Texas Instruments High-Performance Analog
Wideband Frequency Synthesizer with VCO The LMX2581 is an ultra low noise wideband frequency synthesizer which integrates a delta-sigma fractional N PLL, a VCO with fully integrated tank circuit, and an optional frequency divider. The LMX2581 integrates several low-noise, high precision LDOs to provide superior supply noise immunity and more consistent performance. When combined with a high quality reference oscillator, the LMX2581 generates a very stable, ultra low noise signal. The internal VCO can be bypassed so that an external...
