Although this standard is called a 1.5 Gb/s interface, the bit rates supported by HD-SDI are actually 1.485 Gb/s and 1.485/1.001 Gb/s. The SMPTE UHD-SDI core fully supports both of these bit rates. The SMPTE UHD-SDI core also fully supports generation (TX-side) and checking (RX-side) of CRC values for each video line and the insertion (TX-side) and capture (RX-side) of line number values for each line.
