VCSEL driver array
Maturity plannedTargets ASIC (CMOS) onlyDifficulty Very hardPriority 2
Multi-channel VCSEL driver for 850 nm multimode links with bias and modulation current DACs, FFE peaking, NRZ and PAM4 modes and eye safety shutdown.
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 |
| din | in | differential pair | 4 | |
