188.8.131.52. Implementing Multi-Channel x1 Non-Bonded Configuration
This configuration is an extension of the x1 non-bonded case. In the following example, 10 channels are connected to two instances of the PLL IP core. Two PLL instances are required because PLLs using the x1 clock network can only span the 6 channels within the same transceiver bank. A second PLL instance is required to provide the clock to the remaining 4 channels.
Because 10 channels are not bonded and are unrelated, you can use a different PLL type for the second PLL instance. It is also possible to use more than two PLL IP cores and have different PLLs driving different channels. If some channels are running at different data rates, then you need different PLLs driving different channels.
Steps to implement a Multi-Channel x1 Non-Bonded Configuration
- Choose the PLL IP core (ATX PLL, fPLL, or CMU PLL) you want to instantiate in your design and instantiate the PLL IP core.
- Configure the PLL IP core using the IP Parameter Editor
- For the ATX PLL IP core do not include
