The EL4511 super sync separator IC is designed for operation in the next generation of DTV, HDTV, and projector applications, as well as broadcast equipment and other applications where video signals need to be processed. The EL4511 accepts sync on green, separate sync, and H/V sync inputs, automatically selecting the relevant format. It is also capable of detecting and decoding tri-level syncs used with the latest HD systems. Unlike standard sync separators, the EL4511 can automatically detect the line rate and locks to it, without the use of an external RSET resistor. The EL4511 is available in a 24-pin QSOP package and operates over the full 0°C to 70°C temperature range.
The EL4511 sync separator IC processes composite, component, HDTV and PC video signals. It accepts sync on green, separate sync, and H/V sync inputs, automatically selecting the appropriate format and can decode tri‑level syncs used in modern HD systems. The device automatically detects line rate and locks to it without an external resistor.
The chip is supplied in a 24‑pin QSOP package, operates from 3.3 V or 5 V, and supports a maximum line rate of 150 kHz. It is RoHS‑compliant, low‑power, and designed for operation over a temperature range of 0 °C to 70 °C.
