EL4581

Extract timing information and Sakang Broadcasting System from the standard negative video synchronization of NTSC and PAL. It can also be used for non -standard formats and computer graphics systems at a higher scanning speed to adjust an external resistance. When the input does not have a correct jagged pulse in the vertical interval, the default vertical output is generated.

The output includes compound synchronization, vertical synchronization, emergencies/gallery output and strange output. The latter only runs in the interval scan format.

EL4581 provides a reliable method to determine the correct synchronous sliding level, to set it at the midpoint between the synchronous cutting tip and the blank level of the corridor. This 50%level is determined by the two internal self -timing sampling and maintaining circuits, tracking synchronous prompts and the level of the corridor. This also provides a certain degree of buzz and noise suppression for the input signal, and compensates different input levels of 0.5VP-P to 2.0V.

The built -in linear phase, third -order, low -pass filter attenuation in the color signal in the color system to prevent 50%synchronous slides in the colored sudden interference set.

This device can replace industrial standard LM1881, improve performance and reduce power consumption.

EL4581 Video synchronization separator uses ELANTEC's high -performance simulation CMOS process manufacturingEssence
