Nokia C3 HOTTTTTT Discuss





Lets Discuss about C3 phone here


1. Power ic names at this phone is Loviisa and CPUs name is JUNO







2. The Audio Structure System of this phone is very similiar with chinese phone. All Audio part will go directly to CPU which is different from other nokia audio track. Another Nokia audio track is go to Power ic first before to CPU.

Speaker Track


Mic Track


Ihf Speaker (Buzzer) track


3. Simcard way onnokia C3 differs from the other, where if the other nokia sim path of Simcard interface ===> emif (if any) ===> Power Ic ==> CPU, then on the mobile phone has become more simple C3 become Simcard Interface ==> Emif Simcard ==> CPU

4. RF ic of this phone is integrateg inside the CPU, so dont hope u will find RF ic at this phone....





5. Structure Display (LCD) is still the same with other Nokia ... which requires two voltages are Vio 1.8v and Vaux 2.8v, the line detail on these phones from Conector Lcd ==> Emif ==> CPU

6. The Value of RF Clock at this phone is 26 Mhz. its different with another BB5 phone use 38.4Mhz for the RF Clock. Clock oscilator at this phone is not active oscilator , so the signal of rf clock is produced by CPU (because Rf ic is inside CPU)
