2. Jitter is configuration dependent. Actual jitter is dependent on XIN jitter and edge rate, number of active outputs, output frequencies, spread percentage, temper-
ature, and output load. For more information, refer to the application note, “Jitter in PLL Based Systems: Causes, Effects, and Solutions” available at
http://www.cypress.com/clock/appnotes.html, or contact your local Cypress Field Application Engineer.
3. Since the load capacitors (C
and C
) are provided by the CY25100, no external capacitors are needed on the XIN
and XOUT pins to match the crystal load
capacitor (C
). Only a single 0.1-
μ
F bypass capacitor is required on the V
pin.
4. If an external clock is used, apply the clock to XIN (pin 3) and leave XOUT (pin 2) floating (unconnected).
5. If SSON# (pin 8) is LOW (V
SS
), the frequency modulation will be on at SSCLK pin (pin 7).
