Does Maxim have a recommended crystal to use with the MAX14830?
A:
The on-chip crystal oscillator circuit has load capacitance of 16pF (typ) integrated in both XIN and XOUT. A crystal with 3.6864MHz frequency and at least 16pF load will work fine. There are many available crystals. For example, the MAX14830 evaluation kit board has successfully used the ECS-36-20-5PX-TR, which is a 20pF load crystal. https://www.digikey.com/product-detail/en/ecs-inc/ECS-36-20-5PX-TR/XC1236CT-ND/827700
