SGM9125
5-Channel, 5th-Order, Standard
Definition Video Filter Driver
PRODUCT DESCRIPTION
The SGM9125 is a low voltage, 5-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.
SGM9125 offers 6dB gain rail-to-rail output driver and
5th-order output reconstruction filter on all five
channels. It has 8MHz -3dB bandwidth and 35V/µs
slew rate. SGM9125 provides improved image quality
compared with passive LC filters and discrete drivers
solution. Operating from single power supply ranging
from 3.3V to 5.5V and sinking an ultra-low 44mA
quiescent current, the SGM9125 is ideally suited for
battery powered applications.
SGM9125 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 SGM9125
can be configured as DC- or AC-coupled output.
The SGM9125 is available in Green TSSOP-14
package. It operates over an ambient temperature
range of -40℃ to +85℃.
