Description: Dual-SCART Video Switch is Ideal for Low-End, European SCART Set-Top Boxes<<<>>><<<>>>SUNNYVALE, CA-April 24, 2006-Maxim Integrated Products (NASDAQ: MXIM) introduces the MAX7457, a 4-channel video switch. The MAX7457 filters and buffers CVBS, R, G, and B video signals, which makes it ideal for European Dual-SCART set-top boxes with a VCR loop-through. Today, all audio and video switching in European STBs utilize a costly integrated A/V switch offering high-end features, such as volume control and high audio drive capability. A more cost-effective solution uses the MAX7457 for the video switching, along with low-cost standard analog switches for the audio switching. This cost of this latter approach is 50% less than using integrated A/V switching devices.<<<>>><<<>>>The MAX7457 video switch is used in anti-aliasing and DAC-smoothing video applications or wherever analog video is reconstructed from a digital data stream, such as cable/satellite/terrestrial set-top boxes, DVD players, Hard Disk Recorders (HDR), and personal video recorders (PVRs). The device uses a continuous-time, butterworth-type-response lowpass filter to attenuate the sampling frequency of the DAC encoder. All video signal-timing extraction and clamping are done within the device, allowing excellent video performance while saving design time and board space.<<<>>><<<>>>The MAX7457 operates from a single +5V supply and has a flat passband out to 5MHz, ideal for PAL video signals with a stopband of 43dB at 27MHz. The output buffer has a fixed gain of +6dB capable of driving two standard video loads with a 2Vp-p signal. Output disable control is also through an external pin. The MAX7457 is available in the extended (-40° Celsius to +85° Celsius) temperature range, with prices starting at $1.62 (1000 up, FOB USA).
