Pound-Drever-Hall and modulation-transfer error signal generation with a digital PID and lock acquisition for stabilising lasers to cavities or atomic references.
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 |
| pd_in | in | valid-qualified bus | 16 | |
| piezo_out | out | valid-qualified bus | 16 | |
| current_out | out | valid-qualified bus | 16 |
