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 Ld QSOP
package.
Ordering Information
NOTE: Intersil Pb-free plus anneal products employ special Pb-free
material sets; molding compounds/die attach materials and 100%
matte tin plate termination finish, which are RoHS compliant and
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-020.
