Rainbow Electronics MAX9512 User Manual

General Description

The MAX9512 video filter amplifier with SmartSleep™
and Y/C mixer is ideal for portable media players
(PMPs), portable DVD players, and set-top boxes
(STBs). The inputs can be directly connected to the digi­tal-to-analog converter (DAC) outputs. The dual recon­struction filters remove high-frequency signals above

6.75MHz. The Y/C-to-CVBS mixer creates a composite
video signal from luma and chroma. The four amplifiers
each have 6dB of gain. The outputs can be DC-coupled
to a load of 75Ω, which is equivalent to two video loads,
or AC-coupled to a load of 150Ω.

The SmartSleep circuitry intelligently reduces power
consumption based on the presence of the input signal
and the output loads. When the MAX9512 does not
detect the presence of sync on luma, the supply cur­rent is reduced to less than 7µA. The device only
enables a video amplifier when there is an active video
input signal and an attached load. The video amplifier
remains on while a load is connected. If the load is dis­connected, the video amplifier is turned off.

The MAX9512 operates from a 2.7V to 3.6V single sup­ply and is offered in a small, 16-pin TQFN (3mm x
3mm) package. The device is specified over the -40°C
to +125°C automotive temperature range.
