The Great Search: 32 KHz RTC crystals

What this episode covers

We did an earlier Great Search on oscillators, but this week we're specifically looking at 32kHz 'real time clock/counter' crystals. These are often used in microcontrollers as input to a phased-locked loop (PLL) to generate a higher frequency internal clock that is more precise than an RC oscillator. Even though these are not 'semiconductors', they've been quite hard to source! Let's look at what options we've got.
