Notes
1. Refer to the CY22800 generic data sheet for a complete list of AC/DC parameters.
2. Measurements made on CLKA under nominal conditions (VDD = 3.3V, room temperature, 15 pF load cap.) with FS[1:0] = 00.
3. Measurements made under nominal conditions (VDD = 3.3V, room temperature, no load) with FS[1:0] = 00.
4. When ordering from a distributor, use CY22800FXC with the specific code number (032A).
