EL4511
FN7009.8
Super Sync Separator
The EL4511 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.
