+25°C.)

Note 2: All devices are 100% production tested at TA = +25°C. Specifications over temperature limits are guaranteed by design.

Note 3: DC restore is not active. HSYNC and VSYNC are not applied. REST_R, REST_G, and REST_B are grounded.

Note 4: DC restore is active. REST_R, REST_G, and REST_B are bypassed with 1nF to ground.

Note 5: The sync timing error is measured as follows: The input signals are measured from the falling edge of H sync/V sync to the

start of active video, called t1. The output signal is then measured from the falling edge of H sync/V sync to the start of

active video, called t2. All measurements are at the 50% points as shown in Figure 1.
