The ASIC combines everything needed for ToF measurements into one chip requiring a single 5V supply:-
- 32-pixel Avalanche Photodiode (APD) array
- Reference pixel for system health monitoring
- Regulated charge pump for APD bias
- Two laser drivers
- Factory calibrated clock source
- All digital PLL 400MHz
- Logic for timing and integration
- 128bit EEPROM
- Temperature sensors
- Frame based interaction via Serial Peripheral Interface (SPI)
