ISL59451
Triple 4:1 DC Restored Single Supply
Video Multiplexing Amplifier
The ISL59451 is a 4-input, single-supply triple video
multiplexer. It features a DC restore function that makes it
ideally suited for single-supply AC-coupled component video
applications where amplifier headroom is a concern.
When logic “0” is applied to CLAMP, the sample-hold
amplifier loop is closed and the DC level of the amplifier
output is set to the corresponding reference level. This can
occur during sync, or at any time that a black level is
expected. When logic “1” is applied to CLAMP, the clamp is
disabled and the correcting voltage is stored on each video
amplifier’s input coupling capacitor. This DC reference
condition is maintained during the active video period. The
restored DC voltage level can be adjusted over a range of
0V to +3V using external reference voltages applied to the
REF_G and REF_RB pins.
The device features a TTL/CMOS logic compatible gain
select pin (AV2) of x1 or x2. When HIZ is pulled high, the
outputs are put into high-impedance states and the video
inputs are disconnected. This is an essential feature for
power sensitive applications. The ISL59451 also features
channel-switching at pixel rates to allow for video overlays.
The ISL59451 operates from a single +5V supply and is
ideal for +5V systems when used with sync separators such
as the EL1883. The red and blue channels share a common
reference pin (REF_RB) which can also be used to adjust
chroma offsets in YPbPr systems. The green channel has a
separate reference pin (REF_G), which can be used to
accommodate sync-on-green or luma.
The ISL59451 is comes in a 32 Ld QFN package and is
specified for operation over the -40°C to +85°C extended
temperature range.
