MK1709
LOW EMI CLOCK GENERATOR
Unless stated otherwise, VDD = 3.3 V, Ambient Temperature 0 to +85° C
Unless stated otherwise, VDD = 3.3 V, Ambient Temperature 0 to +85° C
For 40 to 50 MHz selections, modulation rate = input frequency/1028; for 50 to 100 MHz selections, modulation rate
= input frequency/2056; for 100 to 165 MHz selections, modulation rate = input frequency/4112.
