TGS MM1671 Low supply voltage 75ohm driver Datasheet

TIGER ELECTRONIC CO.,LTD
Low Supply Voltage 75Ω Driver
MM1671
DESCRIPTIONS
This IC is a 75Ω driver with a built-in LPF that can operate at low voltage. It supports 3V
and 5V operating power voltage, and is ideal for video signal output in devices ranging
fro m portable digital still cameras to stationary equipment such as DVD players . It
incorporates a high performance 4-stage LPF, which is ideal for removing DAC sampling
noise. In addition, ultra-low current consump tion has been achieved by suppressing current
consumption during power save to under 1µA. This lengthens the life of the batteries in
portable devices.
The built-in amp gain on this IC is 6dB and there is also with input cla mp, allowing
support for a range of video signals, not just co mposite signals.
