LTC6905-XXX Series Fixed Frequency SOT-23 Oscillator DESCRIPTIO FEATURES The LTC 6905-XXX series are precision, fixed frequency No External Components to Set Frequency silicon oscillators designed to minimize board space while Frequency Error: 0.5% Typical maximizing accuracy and ease of use. Fast Start-Up Time: 100s Typical 20ppm/C Temperature Stability Programmed at the factory to a fixed frequency, the Includes Output Enable LTC6905-XXX series of parts need no external trim com- Includes Frequency Divide by 1, 2 or 4 ponents. An internal three-state divider allows for division Rise Time: 0.5ns, C = 5pF L of the master clock by 1, 2 or 4, providing 3 frequencies Timing Jitter: <0.8% Typical (for each device). Duty Cycle: 50% 2.5% The LTC6905-XXX series operate with a single 2.7V to I = 8mA Typical (f = 100MHz, C = 5pF) S OSC L 5.5V power supply and provide a rail-to-rail, 50% duty CMOS Output Drives 600 Load cycle, square wave output. The OE pin will disable the Single Supply 2.7V to 5.5V TM output when brought low and synchronously enable the Low Profile (1mm) ThinSOT Package output when brought high, avoiding pulse slivers. U The four products of the LTC6905-XXX family are: APPLICATIO S LTC6905-133: f = 133MHz, 66.7MHz, 33.3MHz OSC Data Clocks for High Reliability Applications LTC6905-100: f = 100MHz, 50MHz, 25MHz OSC High Vibration, High Acceleration Environments LTC6905-96: f = 96MHz, 48MHz, 24MHz OSC Replacement for Fixed Crystal and Ceramic LTC6905-80: f = 80MHz, 40MHz, 20MHz OSC Oscillators The LTC6905-XXX series of parts provides a factory trim , LTC and LT are registered trademarks of Linear Technology Corporation.
