The LTC6905-X 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-X 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-X 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-X 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, 20MHz
The LTC6905-X 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.
