DC Electrical Characteristics
TA = 0°C to +70°C; VDDQ3 = 3.3V±5%; VDDQ2 = 2.5V±5%
Notes:
1. All clock outputs loaded with 6" 60 ohm traces with 22pF capacitors.
2. RC7102 logic inputs have internal pull-up devices (pull-ups not full CMOS level).
3.
X1 input threshold voltage (typical) is VDD/2.
4. The RC7102 contains an internal crystal load capacitor between pin X1 and ground and another between pin X2 and ground.
Total load placed on crystal is 14pF; this includes typical stray capacitance of short PCB traces to crystal.
5. X1 input capacitance is applicable when driving X1 with an external clock source (X2 is left unconnected).
