Description: This article explains the purpose of internal reference generator in ADC for all Nexus products. Solution: The 1.2V internal reference generator is provided to facilitate wafer level and package functional testing. With an accuracy of ...
Solution: Based on Appendix B of FPGA-TN-02129 (ADC User Guide for Nexus Platform), package CSFBGA121 does not support external VREF for both LIFCL-40 and LIFCL-17.
Description:The PLL of the D-PHY hard core will need a stable reference clock as its input. Does Lattice have a recommended accuracy for this reference clock? Solution:There are no specific guidelines as to the recommended accuracy for the reference ...
The Analog-to-Digital Converter (ADC) on the ispPAC-POWR devices has no internal averaging circuit or filtering circuitry. When used in an electrically quiet system, the ADC will typically have less than one LSB of uncertainty, which corresponds to ...
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 ...
