[Paul] likes a precise oscillator. His recent video shows a crystal ... to divide by 10 instead of powers of two to make frequency standards. A 1 MHz crystal can easily generate 100 kHz, 10 ...

IP is a low power high resolution RC oscillator nominally operates at 1.024 MHz output clock from a 1.2 V supply. No external components are required. The oscillator operates in a voltage range of 1.2 ...

For that you might reach for something like an oven oscillator, a circuit with a temperature controlled chamber able to keep incredibly precise time. [IMSAI Guy] found this 10 MHz oven oscillator ...
