NOTES:

1 Conditions for these values are V

DD_HV_IOx = 3.3 V (–5%, +10%), TJ = –40 / 150 °C

2 All values need to be confirmed during device characterization.

3 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.

4 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.

5 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.
