SPAD array readout
Maturity plannedTargets ASIC (CMOS) onlyDifficulty Very hardPriority 1
Quenching, recharge and pulse shaping for single-photon avalanche diode pixels with per-pixel or shared TDCs and event readout.
Planned. This block is specified in the catalog with its interfaces and targets. No implementation exists yet; the skeleton command below generates a lint-clean shell with its ports and registers.
Interfaces
| Port | Direction | Kind | Width | Notes |
|---|---|---|---|---|
| ctrl | in/out | APB control bus | 32 | Control and status registers, including ID, VERSION and STATUS |
| irq | out | interrupt | 1 | Interrupt request |
| spad | inout | analog | 64 | |
| events | out | AXI4-Stream | 32 |
Standards
No external standard applies.
