Micro SwinSID PCB v1.0 | ||||||||||
Here is the schematics and PCB layout of the Micro SwinSID based on ATMEGA88. This is minimalistic version of SwinSID. It contains only clock generator, AVR, few resistors and single voltage filtering capacitor. To minimize complexity it was designed to work only with C64 internal output. This remains original output stage already tested by Crisp. PWM lowpass filtering is done in C64 by RC filter before the output transistor. |
