DESCRIPTION
Buffered crystal oscillator frequency output
D clock output
CPU PLL output with controlled frequency slew rate
A clock output
B clock output
Ground
Frequency select control input for the CLK_CPU output
Frequency select control input for the CLK_CPU output
Power supply (5V to 3.3V)
Active-low control input powers-down selected PLLs and outputs
Output enable input: logic-high enables outputs; logic-low tristates outputs (high impedance)
