of_ams_clk_tree_buf
Clock buffer and divider tree
Maturity plannedTargets ASIC (CMOS) onlyDifficulty MediumPriority 2
Low-skew clock fanout buffer with per-output programmable integer dividers, CML-to-CMOS conversion and glitch-free enable.
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 |
| clkin | in | differential pair | 1 | |
| clkout | out | clock | 8 |
Standards
No external standard applies.
