The EL1881CSZ is a Synchronization Separator Video IC from Renesas. It is designed to separate vertical and horizontal sync pulses and generate a DC reference voltage for amplitude control. It is designed to work with a variety of video formats such as PAL, NTSC, and SECAM. The EL1881CSZ includes features such as automatic amplitude level adjustment, 75 ohm termination, automatic noise reduction, active-low AC-coupling and active-high DC-coupling output pins for improved performance and accurate synchronization. The IC also has a low standby power rating, making it suitable for portable and mobile applications.
