VCSEL current and temperature control, microwave interrogation and lock-in detection for a coherent population trapping cesium cell.
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 | inout | analog | 1 | |
| vcsel | inout | analog | 1 | |
| rf_mod | inout | RF | 1 |
Standards
No external standard applies.
Notes
Candidate for Dyber, Inc. GaAs VCSEL capability.
