AC Electrical Characteristics
TA = 0°C to +70°C, VDDQ3 = 3.3V±5%, fXTL = 14.31818 MHz
AC clock parameters are tested and guaranteed over stated operating conditions using the stated lump capacitive load at the
clock output; Spread Spectrum is disabled.
Notes:
5. X1 input threshold voltage (typical) is VDD/2.
6. The CY28317-2 contains an internal crystal load capacitor between pin X1 and ground and another between pin X2 and ground. The total load placed on the
crystal is 18 pF; this includes typical stray capacitance of short PCB traces to the crystal.
7. X1 input capacitance is applicable when driving X1 with an external clock source (X2 is left unconnected).
8. Determined as a fraction of 2* (tRP – tRN). Where tRP is a rising edge and tRN is an intersection falling edge.
