13. Xtal inputs have CMOS thresholds.
14. Load = Max., V
15. XBUF duty cycle depends on XTALIN duty cycle.
16. Measured at 1.4 V.
17. Measured between 0.4V and 2.4 V.
18. Please refer to application note “Understanding the CY2291, CY2292 and CY2295” for more information.
19. Jitter varies with configuration. All standard configurations sample tested at the factory conform to this limit. For more information on jitter, please refer to the application
20. CLKF is not guaranteed to be in phase with CLKA-D, even if it is referenced off the same PLL
