gullradriel	8f5b25b10d	PRALINE Tx and clock fix (Pr 3192 takeover (#3198 ) ) * fix clock init and add mayhem tx capacity * aligned external clock and RX config * fix(clock): cap TX interpolation to x16 to prevent doubled waveform speed The TX gateware only implements interpolation factors x1..x16 (tx_intrp 0..4), but the rate search could select n==5 (x32) for very low TX sample rates. That left the AFE/CLK0/CLK1 running at the x32 rate while the FPGA only interpolated by x16, clocking the TX datapath at twice the gateware output rate. Cap afe_rate and _resampling_n to the x16 limit in TX so the clocks stay aligned with the interpolation setting. * fix(praline): source PLL1 from 40MHz GP_CLKIN instead of 12MHz XTAL For the intermediate 90-110MHz PLL1 stepping stage, source PLL1 from GP_CLKIN (Si5351 CLK2/MCU_CLK at 40MHz) giving N=2, M=10, Fclk=100MHz, rather than the on-chip 12MHz XTAL bootstrap path. This matches the non-PRALINE path. Remove the dead commented-out XTAL enable/PLL code. * docs(fpga_bridge): correct register 0x03 description for PRALINE gateware Register 0x03 is RX_DIGITAL_GAIN in RX and TX_NCO_CTRL in TX, not RX_PSTEP. * Fix fpga_tx_set_nco_enable to use FPGA_REG3_TX_NCO_CTRL (0x03)	2026-05-31 12:44:40 +02:00
