1x Active Crystal Oscillator Output Board Module Direct Frequency Output 3.3V-5VItem Details1pcs Active Crystal Oscillator Output Board Module Direct Frequency Output 3.3V-5VDescription:Notice: Just 1pcs Active Crystal Oscillator Output Board, Not Contain Any Crystal Oscillator.The module can directly output crystal frequency, supports three different active crystal package, suitable for most of the crystal.Active crystal oscillator has four pins is a complete oscillator, which in addition to quartz crystal, there are transistors and RC components.Active crystal oscillator does not require DSP's internal oscillator, the signal quality is good, relatively stable, and the connection is relatively simple (mainly to do the power supply filter, usually using a capacitor and inductor form PI-type filter network, The output filters the signal with a small resistance value), does not require complicated configuration circuit.Active crystal relative to the passive crystal oscillator, active crystal defect is its signal level is fixed, you need to select a good output level, poor flexibility, the price is relatively high.Sensitive applications for timing requirements, or good active crystal, so you can use the more sophisticated crystal, or even a high-end temperature compensation crystal.Features:Name: Active Crystal Oscillator Output BoardBoard Size: 41mm x 16mmActive Crystal Size: 5mm x 7mmPower Supply: 3.3V-5.0VPacking List:1pcs x Active Crystal Oscillator Output BoardAbout PaymentAbout DeliveryAbout ReturnsAbout responseContact usAbout PaymentPlease leave note for your special request (e.g. Colors or Size) in when you pay the order.Any special request cannot be accepted after 24 hours of payment, because most of orders will be processed instantly and same day dispatched.About DeliveryItem will be shipped within one business day after full payment is received.Except The United States and Russia we shipped use Epack, We ship worldwide with standard shipping by Hong Kong Air mail.
