7.3.12 JESD204B Interface Initialization Sequence
After power-up, the internal JESD204B digital block must be initialized with the following sequence of steps:
- Set JESD RESET AB/CD and JESD INIT AB/CD to 0 (address 0x0D, value 0x0000)
- Set JESD INIT AB/CD to 1 (0x0D, 0x0202)
- Set JESD RESET AB/CD to 1 (0x0D, 0x0303)
- Configure all other JESD register and clock settings. If those settings change later on, this initialization sequence must be repeated.
- Set JESD RESET AB/CD to 0 (0x0D, 0x0202)
- Set JESD RESET AB/CD to 1 (0x0D, 0x0303)
- Wait for two SYSREF pulses
- Set JESD INIT AB/CD to 0 (0x0D, 0x0101)
