Product details
Overview
LTC6905IS5-96#TRPBF from Analog Devices (formerly Linear Technology) is a precision fixed-frequency silicon oscillator in ThinSOT-23 package, delivering factory-trimmed output frequencies of 96MHz, 48MHz, and 24MHz via internal ÷1/÷2/÷4 divider. It operates from 2.7V to 5.5V, features ±0.5% typical frequency accuracy at 25°C, ±20ppm/°C temperature stability, and 0.5ns rise/fall time into 5pF load - used for clocking high-reliability data interfaces in vibration-prone industrial systems.
For engineers reviewing the LTC6905IS5-96#TRPBF datasheet, LTC6905IS5-96#TRPBF pinout, LTC6905IS5-96#TRPBF application, or LTC6905IS5-96#TRPBF equivalent, key selection criteria include its rail-to-rail CMOS output driving 600Ω loads, synchronous OE-controlled enable/disable, fast 100µs start-up, and guaranteed performance over –40°C to 85°C industrial temperature range.
Technical Context
The LTC6905IS5-96#TRPBF integrates a master oscillator with programmable three-state divider (N = 1, 2, or 4), enabling three discrete output frequencies from a single device. Its internal bias circuit maintains VRES = 1V ±5%, ensuring stable frequency generation independent of supply voltage drift within specified limits.
It uses asynchronous OE control for immediate output disable and synchronous rising-edge enable to eliminate pulse slivers; DIV pin detection relies on dual 15µA current sources (to V+ and GND) to reliably distinguish high, low, and floating states without external pull resistors.

FAQ
What are the exact output frequencies supported by the LTC6905IS5-96#TRPBF?
The LTC6905IS5-96#TRPBF delivers three factory-programmed output frequencies: 96MHz when DIV = V+, 48MHz when DIV is floating, and 24MHz when DIV = GND. These correspond to internal divide-by-1, divide-by-2, and divide-by-4 configurations of the master oscillator. All frequencies are trimmed at the factory and require no external components to set or adjust.
Does the LTC6905IS5-96#TRPBF support operation across the full industrial temperature range?
Yes, the LTC6905IS5-96#TRPBF is rated for operation from –40°C to +85°C and is fully specified over this range for parameters including supply current, output voltage levels, and timing jitter. Frequency accuracy is guaranteed at ±2.9% over –40°C to 85°C, with ±0.5% typical at 25°C.
How does the OE pin function on the LTC6905IS5-96#TRPBF?
The OE (Output Enable) pin on the LTC6905IS5-96#TRPBF provides asynchronous disable and synchronous enable: pulling OE low immediately disables the output driver, while pulling OE high enables the output on the next rising edge of the internal clock - preventing pulse slivers. This behavior is confirmed in the functional description and timing diagrams of the official datasheet.
Can the LTC6905IS5-96#TRPBF drive a 50Ω transmission line directly?
No, the LTC6905IS5-96#TRPBF CMOS output is not designed to drive 50Ω loads directly. Its minimum resistive load is 600Ω at 2.7V (per Electrical Characteristics). To drive a 50Ω cable, an external buffer or series termination (e.g., 950Ω resistor per Typical Application diagram TA02) must be used to match impedance and prevent reflections.
What is the start-up time specification for the LTC6905IS5-96#TRPBF?
The LTC6905IS5-96#TRPBF achieves frequency stability within 1% of final value in 100µs typical after power-on or OE activation. This start-up time is measured under standard conditions (V+ = 3V, CL = 5pF) and is consistent across all three output frequencies (96MHz, 48MHz, 24MHz).
