LTC6905-XXX中文资料固定频率 SOT-23 封装振荡器数据手册ADI规格书

描述 Description

The LTC®6905-XXX series of parts are precision, fixed frequency, silicon oscillators designed to minimize board space while maximizing accuracy and ease of use.Programmed at the factory to a fixed frequency, the LTC6905-XXX series of parts need no external trim components. An internal three-state divider allows for division of the master clock by 1, 2 or 4, providing 3 frequencies (for each device).
The LTC6905-XXX series operate with a single 2.7V to 5.5V power supply and provide a rail-to-rail, 50% duty cycle, square wave output. The OE pin will disable the output when brought low and synchronously enable the output when brought high, avoiding pulse slivers.
The four products of the LTC6905-XXX family are:
LTC6905-133: fOSC = 133MHz, 66.7MHz, 33.3MHz LTC6905-100: fOSC = 100MHz, 50MHz, 25MHz LTC6905-96: fOSC = 96MHz, 48MHz, 24MHz LTC6905-80: fOSC = 80MHz, 40MHz, 20MHzThe LTC6905-XXX series of parts are designed with a factory trim option to modify the divider ratios from 1, 2, 4 to 8, 16, 32. A second trim option allows for additional master clock frequencies. For the alternate divider ratios and unlisted frequencies, contact LTC marketing.
