SGM9149
13MHz, Triple-Channel, 5th-Order,
Standard Definition Video Filter Driver
PRODUCT DESCRIPTION
The SGM9149 is a low voltage, triple channel video
amplifier with integrated reconstruction filters and input
clamps. Specially suited for standard definition video
signals, this device is ideal for a wide range of
television and set-top box applications.
SGM9149 offers 6dB gain rail-to-rail output driver and
5th-order output reconstruction filter on all three
channels. It has a -3dB bandwidth of 13MHz and
61V/µs slew rate. SGM9149 provides improved image
quality compared with passive LC filters and discrete
drivers solution. Operating from single power supply
ranging from 3.0V to 5.5V and sinking a low 21mA
quiescent current, the SGM9149 is ideally suited for
battery powered applications.
SGM9149 can be DC-coupled or AC-coupled with input
video signal, such as the output stage of DAC to
eliminate out-of-band noise. The output in SGM9149
can be configured as DC- or AC-coupled output.
The SGM9149 is available in Green SOIC-8 and
MSOP-8 packages. It operates over an ambient
temperature range of -40℃ to +85℃.
