&10;We have text on a faded neutral background, evocative of the desert. Here is the text:&10;&10;LVDS vs CMOS is fundamental: The 4× clock difference isn't a bug — it's how LVDS works. Designs must account for it.&10;BUFR has hard limits: Regional clock buffers cannot drive large designs. BUFG (global buffer) is required for anything substantial.&10;Valid signal gating is fragile: The dac_valid_i0 / adc_valid_i0 approach depends on undocumented ADI IP behavior that varies by mode (1R1T vs 2R2T, LVDS vs CMOS).&10;Clock divider approach is robust: By running the MSK modem at the actual sample rate (61.44 MHz), we sidestep all the valid-signal timing quirks. Every clock cycle IS a valid sample.&10;Device tree must match HDL: The 2R2T attempt failed because the device tree was configured for 1R1T. HDL and software must agree.
