Setup Of Input Frequency; Connection Example Of Oscillator - Panasonic MN103S User Manual

3.3.2

Setup of Input Frequency

Input frequency range of clock generator is 5 MHz (minimum) and 15 MHz (maximum). When the input clock is
multiplied, the PLL output frequency (PLLOUT) needs to be set to be 40 MHz to 60 MHz. Table: 3.3.3 shows the
input frequency and PLL multiple magnification to be set.
