ZHCSFY7B January 2017 – December 2021 ADS58J64
PRODUCTION DATA
The initial lane alignment process is started by the receiving device by deasserting the SYNCb signal. When a logic low is detected on the SYNC input pins, the ADS58J64 starts transmitting comma (K28.5) characters to establish code group synchronization, as shown in Figure 7-23.
When synchronization is complete, the receiving device reasserts the SYNCb signal and the ADS58J64 starts the initial lane alignment sequence with the next local multi-frame clock boundary. The ADS58J64 transmits four multi-frames, each containing K frames (K is SPI programmable). Each of the multi-frames contains the frame start and end symbols and the second multi-frame also contains the JESD204 link configuration data.
