Bidirectional Video Filters/Buffers for Composite  
and S-Video Portable Media Devices  
1/MAX7482  
General Description  
Features  
The MAX7481/MAX7482 bidirectional video filters/  
buffers provide the reconstruction filter and line drive  
buffer for both composite (CVBS) and S-Video (Y/C)  
video signals in playback mode, and anti-aliasing in  
record mode for portable media devices. Each channel  
consists of a lowpass filter and an output buffer capa-  
♦ Composite and S-Video, Video-Playback and Video-  
Record Interface for Portable Video Devices  
♦ Saves Space by Sharing Connectors in Portable  
Devices  
♦ DirectDrive  
Eliminates Expensive AC-Coupling Capacitors  
Blanking Level at Ground with Single Supply  
ble of driving a full 2V  
video signal into one standard  
P-P  
150Ω load (DC-coupled to ground). In record mode,  
the MAX7481/MAX7482 output buffers have a gain of  
+6dB. In playback mode, the MAX7481 output buffers  
have a gain of +6dB and the MAX7482 output buffers  
have a gain of +7dB.  
♦ Composite and Y/C Signals  
♦ Advanced Power-Down Modes for Extended  
Battery Life  
♦ Low Supply Current in Shutdown Mode, < 1µA (typ)  
♦ Filter Response Ideal for NTSC and PAL  
♦ +6dB (MAX7481) or +7dB (MAX7482) Gain  
♦ +2.7V to +3.6V Single-Supply Operation  
♦ Small, 28-Pin, TQFN Package (5mm x 5mm)  
Ordering Information  
The MAX7481/MAX7482 feature DirectDrive™ by utilizing  
an internal negative charge pump and regulator to main-  
tain the output blanking level at ground, eliminating the  
need for a negative supply voltage, a large output cou-  
pling capacitor, or a sag correction configuration.  
The MAX7481/MAX7482 operate from a single +2.7V to  
+3.6V power supply. These devices are available in a  
space-saving 28-pin TQFN package and operate over  
the -40°C to +85°C extended temperature range.
