3.3.2. Clock oscillator circuit for 2 clock/ECK master MCK PLL
Operate the CXD3172AR with two clocks: the encoder clock (ECK), oscillated by X'tal, and the driving system
clock (MCK), oscillated by PLL.
shows the configuration and evaluation board circuit constants (
) for a clock oscillator
circuit for MCK PLL using X'tal.
