Note 2: All devices are 100% production tested at T
A
= +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.
