Aurora LVDS interface timing specifications Symbol C Parameter Value Unit Min Typ Max Data Rate — SR T Data rate — — 1250 Mbps STARTUP tSTRT_BIAS CC T Bias startup time(1) —— 5 µs tSTRT_TX CC T Transmitter startup time(2) —— 5 µs tSTRT_RX CC T Receiver startup time(3) —— 4 µs 1. Startup time is defined as the time taken by LVDS current reference block for settling bias current after its pwr_down (power down) has been deasserted. LVDS functionality is guaranteed only after the startup time. 2. Startup time is defined as the time taken by LVDS transmitter for settling after its pwr_down (power down) has been deasserted. Here it is assumed that current reference is already stable (see Bias start-up time). LVDS functionality is guaranteed only after the startup time. 3. Startup time is defined as the time taken by LVDS receiver for settling after its pwr_down (power down) has been deasserted. Here it is assumed that current reference is already stable (see Bias start-up time). LVDS functionality is guaranteed only after the startup time. Table 52.
