Epson has a passive SMT crystal oscillator with an external size of 3.2 * 2.5mm, model TSX-3225, which is also very intuitive and can distinguish its packaging size from the model. It is widely used in portable wireless transmission devices. At the same time, this is also a very mature product. After all, SMD3225 packaging is currently the mainstream packaging in the market. TSX-3225 product is a high-performance and high-precision SMT crystal oscillator, which is trusted and popular in various products and application environments.
TSX-3225 has one advantage, which is its lower cost. Nowadays, the electronic component market is trending towards miniaturization. Although EPSON Epson has developed the 16122520 SMT crystal oscillator, which is smaller than the 3225 package, the smaller size also means that the manufacturing process is complex, more investment is required, and the cost is higher. In the application of some portable terminal electronic products, the cost and packaging performance of 3225 SMT crystal oscillator packaging perfectly meet the current market. It is a relatively affordable passive SMT crystal oscillator in the entire passive crystal oscillator packaging size. The widely used and affordable crystal oscillator packaging also represents its wide popularity. Therefore, the brand substitutability of choosing 3225 SMT crystal oscillator packaging is also relatively flexible. Of course, the TSX-3225 crystal oscillator is a frequency component that can handle frequencies ranging from 16-48MHz.
Among them, TSX-3225 24MHz 12PF ± 10PPM and TSX-3225 16MHz 12PF 10PPM are two commonly used crystal oscillators, with a working temperature range of -40/85 ℃, which is a standard industrial grade SMT crystal oscillator. In addition, TSX-3225 30MHz 9PF is also frequently used as an external crystal oscillator for wireless transceivers, because at the 30MHz frequency point, TSX-3225 is well adapted to the si4438 wireless transceiver, and S14438 defaults to using the 30MHz passive crystal. The initial frequency accuracy of TSX-3225 30MHz reaches+10ppm at+25 ° C, with a working temperature range of -40~85 ° C. The variation in clock accuracy within the range of -20 ° C~75 ° C is less than (+10ppm). In addition, the TSX-3225 is loaded with a 9PF small capacitor, with high accuracy and strong stability, making it very suitable for the design of wireless transceiver blocks.
