Crystal Specification of the HX2 (CY7C65640/CY7C65640A)

Last Updated: May 19, 2011

What is the crystal required specification with the HX2 (Cy7C65640/CY7C65640A)?


When a 24 MHz (± 0.05%) crystal is used in the design, Cypress recommends that for proper operation the load capacitance of the crystal should be between 20 pF and 33 pF. This affects both the load capacitors and the crystal being used.
