The XT is a quartz-based PLL oscillator with integrated TCXO with a key focus on stability. The XT family has frequency stability as tight as ±3ppm for -40 °C to +85 °C and life stability of ±13ppm. It is ideal for enterprise-level equipment that demands low noise, stable, and accurate timing/clock sources such as transceiver module or data center.

XT 是集成有 TCXO晶振是穩(wěn)定性極佳的石英 PLL 振蕩器。 XT 系列在 -40°C 至 +85°C 范圍內(nèi)的頻率穩(wěn)定性為 ±3ppm，壽命穩(wěn)定性為 ±13ppm。此系列特別適用于需要低噪聲、穩(wěn)定和精確時鐘源的工業(yè)級設備（比如收發(fā)器模塊或數(shù)據(jù)中心）。

Short lead-time, low noise, wide frequency range, excellent ambient performance, and very little engineering effort to incorporate this into your design make the XT series an excellent choice over the conventional technologies. The XT family provides extremely quick delivery for both standard and custom frequencies.

交付周期短、噪聲低、頻率范圍寬、環(huán)境性能優(yōu)異，只需要極少的工程工作量，即可將其融入到您的設計中，這使得 XT 系列成為超越傳統(tǒng)技術的最佳選擇。無論是標準頻率還是自定義頻率，XT 系列均可實現(xiàn)快速交付。
