Sunnyvale, Calif.Maxim Integrated Products has introduced the MAX11500 3-channel HD video filter, the MAX11501/MAX11502 3-channel SD video filters, and the MAX11504/MAX11505 4-channel SD video filters.
The HD and SD video filters integrate input clamps, output buffers, and ±12kV ESD protection to reduce cost, improve reliability, and save space. The MAX11500 and MAX11501/MAX11502/ MAX11504/ MAX11505 are well-suited for anti-aliasing and DAC-reconstruction digital-video applications, such as set-top boxes (STBs), personal video recorders (PVRs), and HD and SD televisions.
The MAX11500 supports HD (1080i/720p) and the MAX11501/MAX11502/MAX11504/MAX11505 support SD (NTSC/PAL) scanning standards. The MAX11500 is a 6th-order 33MHz HD filter that accommodates component video (YPbPr and RGB); the MAX11501/MAX11502/MAX11504/MAX11505 are 5th-order SD filters that accommodate component video (YPbPr, RGB, and S-video or Y/C) and composite video (CVBS). The MAX11501/MAX11504 offer a flat passband with an 8.6MHz bandwidth, while the MAX11502/MAX11505 provide a high-frequency boost passband with an 8.9MHz bandwidth to compensate for DAC rolloff.
