Hi,
I am trying to program CDCE913 to generate frequencies from low MHz to 230 MHz range. I observe that it works perfectly till 135 MHz(N/M = 5/1) but as soon as I increase N to 6, the frequency falls to 108 MHz instead of expected 162 MHz. EEPROM is programmed to 135 MHz.
My register settings are (I am doing a byte write for each register offset, CC:command code , Data: the data on the register)
if(CC == 0x83){Data = 0x0A; }
else if(CC == 0x84){Data = 0x02; }
else if(CC == 0x85){Data = (0x0F)<<3; }
else if(CC == 0x86){Data = 0x05;}
else if(CC > 0x86 && CC <0x10) {Data = 0;}
else if(CC == 0x90){Data = 0; }
else if(CC == 0x91){Data = 0; }
else if(CC == 0x92){Data = 0; }
else if(CC == 0x93){Data = 0x00; }
else if(CC == 0x94){Data = 0x6F; }
else if(CC == 0x95){Data = 0x02; }
else if(CC == 0x96){Data = 0x0A; }
else if(CC == 0x97){Data = 0x0A; }
else if(CC == 0x98){Data = 0x00; }
else if(CC == 0x99){Data = 0x60; }
else if(CC == 0x9A){Data = 0x03; }
else if(CC == 0x9B){Data = 0x0A; }
else if(CC == 0x9C){Data = 0; }
Thanks,
Gunjan
