Part Details:

19-3560; Rev 0; 1/05 Video Switch for Dual SCART Connectors MAX7457 General Description Features The MAX7457 4-channel video switch is ideal for anti- 4-Channel Video Filter/Buffer for RGB and CVBS aliasing and DAC-smoothing video applications or wher- Signals with Auxiliary Input ever analog video is reconstructed from a digital datastream such as cable/satellite/terrestrial set-top boxes Allows Auxiliary Input for CVBS Video Loop- (STBs), DVD players, hard disk recorders (HDRs), and Through Applications personal video recorders (PVRs). The MAX7457 filters Filter Response Ideal for NTSC, PAL, and and buffers CVBS and RGB video signals, making it Interlaced SDTV Video Signals ideal for dual SCART (peritelevision) STBs with an auxiliary CVBS input. The MAX7457 operates from a sin- 43dB (typ) Stopband Attenuation at 27MHz gle +5V supply and has a flat passband out to 5MHz ±0.75dB (max) Passband Ripple Out to 5MHz with a stopband attenuation of 43dB at 27MHz, makingit ideal for NTSC, PAL, and standard-definition digital TV Blanking Level Voltage on Cable <1V (SDTV) video systems. Each Channel Drives Two 150 Video Loads The MAX7457 output buffers have a fixed gain of +6dB +5V Single-Supply Operation and are capable of driving two standard 150 videoloads. The channel for CVBS video has high-frequency Available in 5mm x 5mm x 0.8mm, 16-Pin TQFN boost circuitry that enhances picture sharpness with upto +1.2dB of gain boost without degradation in thestopband. The video output drivers can be disabled by Ordering Information an external control input. PKG The MAX7457 is available in a 16-pin, 5mm x 5mm x PART TEMP RANGE PIN-PACKAGE CODE 0.8mm TQFN package, and is specified over theextended (-40°C to +85°C) temperature range. MAX7457ETE -40°C to +85°C 16 TQFN-EP* T1655-2 Applications *EP = Exposed pad. STBs/HDRs DVD Players Game Consoles Digital VCRs Pin Configuration appears at end of data sheet.
