09 September 2015 Question by: s | Product code: 90-3636
Q. is the product specified as fundamental mode or 3rd overtone.The datasheet says both are available. 3rd ot means operating at 3 times the fundamental frequency, requiring different drive circuitry to run at the specified frequency. using such circuitry with a fundamental mode crystal would result in (approx)81 Mhz.
A. Hi S, thank you for your question. These are the fundamental type crystals.
