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. 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
