TIGER ELECTRONIC CO.,LTD Low Supply Voltage 75 Ω D river MM 1671 D ESCRIPTIONS T his IC is a 75 Ω d river 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.
