100 MHz fixed-frequency clock source in a 5-pin TSOT-23-5
No external timing components are needed — the frequency is set at the factory. This makes it a drop-in replacement for crystal-based oscillators in applications where board space is tight and the frequency tolerance of a silicon oscillator is acceptable. The TSOT-23-5 package occupies roughly 3 mm × 3 mm, which frees layout area compared to a canned crystal oscillator. The output is a rail-to-rail CMOS-level signal, so it drives most MCU clock inputs, FPGA reference clocks, or timing inputs directly without external level shifting.
Supply range and temperature grade — where it fits on the board
At 8 mA supply current, the LTC6905IS5-100#TRMPBF adds about 40 mW to the power budget at 5 V — negligible in a mains-powered system but worth noting in battery-operated designs where every milliamp counts. The silicon oscillator architecture eliminates the startup settling time of a crystal, so the clock is valid within microseconds of power-on.
