Please refer to Section 9. Soft IP Modules of the FPGA-TN-02097 (CrossLink-NX High-Speed I/O Interface Technical Note). The said Soft IPs are used in Generic DDR IP depending on the Interface as seen in Table 9.2.Soft IP Used in Each Interface. After ...
Description:This article explains the reason ADC clock-in cannot be driven using an oscillator output in CertusPro-NX. Solution:In CertusPro-NX., the ADC clock input is hard-wired on the fabric to the 4th secondary output (CLKOS4) of the Lower Right ...
Users have a couple of options for their design to use the CrossLink-NX evaluation board: 1. Use an external clock from a different clock pin: Instead of using the onboard oscillator, users can connect one of the other PCLK pins as input to the FPGA ...
It is common for most of today’s FPGA’s to provide multiple PLLs to support the flexible clock requirements needed for today's complex system design. The PLL has a specific frequency operational range. For example, the LatticeXP2 datasheet indicates ...
When the PLL is in power down (default when it is not used), the current to PLL is turned off, and the VCO and Charge Pump is not running. After programming completes, there is a dedicated global bit to disable the oscillator. Oscillator is turned ...
