Video Front End
The EL4501 is a highly-integrated
Video Front End (VFE) incorporating
all of the key signal conditioning
functions for analog video signals. It provides a flexible front-
end interface for analog or analog/digital video sub-systems.
The VFE contains a high bandwidth DC-restore, an
advanced sync separator and a data slicer with an
adjustable threshold, configurable output and power-down
mode.
The VFE performs restoration of the DC level (blanking
level) of a video signal and the recovery of all signal timing
necessary for synchronization and control. Additionally, data
embedded in the active video or VBI regions of the video
signal may be extracted using the flexible data slicer
incorporated into the VFE. The advanced sync separator
exhibits excellent noise immunity by incorporating a digital
brick wall filter and signal qualification algorithm. The DC-
restored video amplifier is unity gain stable with an unloaded
-3dB bandwidth of 100MHz. The input common mode
voltage range extends from the negative rail to within 1.5V of
the positive rail. When driving a 75Ω double terminated
coaxial cable, the amplifier can drive to within 150mV of
either rail. With 200V/µs slew rate, the amplifier is well suited
for composite and component video applications.
The VFE operates from a single 5V supply from -40°C to
+85°C and is available in a reduced footprint 24-pin QSOP
package.

NOTE: Intersil Pb-free products employ special Pb-free material
sets; molding compounds/die attach materials and 100% matte tin
plate termination finish, which is compatible with both SnPb and
Pb-free soldering operations. Intersil Pb-free products are MSL
classified at Pb-free peak reflow temperatures that meet or exceed
the Pb-free requirements of IPC/JEDEC J Std-020B.
