LTC6930-X.XX 32.768kHz to 8.192MHz Precision µPower Oscillators FEATURES n n n n n n n n DESCRIPTION The LTC®6930 series is a family of very low power precision silicon oscillators with a frequency error less than 0.09%. For each oscillator, the user can select one of 8 frequencies between 32.768kHz and 8.192MHz. Based on a fixed master oscillator frequency, internal frequency dividers between 1 and 128 provide the 8 different frequencies. The LTC6930 requires no external components other than power supply bypass capacitors. Requiring only a single 1.7V to 5.5V supply enables operation from a single Li-Ion cell or 2 AA alkaline cells. The LTC6930 features a proprietary control architecture that allows for ultra-low power operation while maintaining industry leading accuracy and jitter specifications. The exceptionally fast start-up time, combined with the low power consumption, is ideal for battery operated applications with frequent power-up cycles. Any frequency from 32.768kHz to 8.192MHz can be provided by the factory. Minimum order sizes apply for custom frequencies. Please consult LTC Marketing for details.

1. 物料型号: - LTC6930-X.XX系列,其中X.XX表示不同的频率版本,例如LTC6930-4.19表示4.194304MHz的频率。

2. 器件简介: - LTC6930系列是一款超低功耗、高精度的硅振荡器,频率误差小于0.09%。用户可以在32.768kHz到8.192MHz之间选择8种不同的频率。基于固定的主振荡器频率,内部频率分频器提供8种不同的频率。LTC6930只需要1.7V到5.5V的单电源供电,不需要外部组件,除了电源旁路电容器。

3. 引脚分配: - V+(引脚1、8):正电源引脚。每个电源引脚应直接连接到相邻的GND引脚,并需要外部连接到另一个V+引脚。 - GND(引脚2、6):地引脚。每个引脚应连接到低感地面,并需要连接到另一个GND引脚以及DFN封装的引脚9。 - DIVA, DIVB, DIVC(引脚3、4、5):输出预分频器。用于选择主振荡器频率的分频比,以生成输出频率。

4. 参数特性: - 频率误差:最大0.09%。 - 启动时间:所有频率下小于110μs。 - 供电电流:在32kHz时典型值为105μA,在8MHz时典型值为490μA。 - 工作温度范围:-40°C至125°C。

5. 功能详解: - LTC6930包含一个主振荡器、一个控制环和一个输出频率分频器。主振荡器在4.2MHz到8.2MHz之间工作,由工厂预设。输出频率分频器由DIVA、DIVB和DIVC输入控制,分频比为$2^N$,其中N为0到7之间的整数。

6. 应用信息: - LTC6930适用于数字控制振荡器、微处理器时钟、电源时钟、便携式和电池操作设备等应用。

7. 封装信息: - 提供2mm×3mm的DFN封装和8引脚的MSOP封装。
