MAXIM Integrated Products, represented by Arrow Electronics , has introduced the MAX7440/MAX7441/MAX7442 six-channel video reconstruction filters.
These devices are suitable for anti-aliasing and digital-to-analogue (DAC) reconstruction video applications such as set-top boxes, DVD players, hard-disk recorders (HDR), and personal video recorders (PVRs).
Each channel of the MAX7440/MAX7441/MAX7442 combines a continuous-time lowpass filter with high-frequency boost options and a unity-gain amplifier.
High performance and integration make these devices ideal for European STBs using SCART connectors.
The MAX7440/MAX7441/MAX7442 support composite video (CVBS), S-Video (Y/C), and component (RGB or Y Pr Pb) video signals for both NTSC and PAL.
The filter achieves 40dB of stopband rejection at 27MHz with a maximally flat passband of only ±0.5dB ripple.
High-frequency boost circuitry provides picture sharpness adjustment without degradation in the stopband attenuation.
These devices save significant board space and insertion costs by replacing up to 30 discrete components.
Providing excellent video performance, the MAX7440/MAX7441/MAX7442 are packaged in a 14-pin SO in the -40°C to +85°C extended temperature range.
