说明

Fabricated using the new complimentary silicon-germanium (SiGe) BiCom-III process, the THS7353 is a low-power, single-supply 2.7-V to 5-V, 3-channel integrated video buffer. It incorporates a selectable 5^th order Butterworth anti-aliasing / DAC reconstruction filter to eliminate data converter images. The 9-MHz is a perfect choice for SDTV video including composite, S-Video, and 480i/576i Y'P'_BP'_R or G'B'R' (R'G'B') video. The 16-MHz filter is ideal for EDTV 480p/576p Y'P'_BP'_R, G'B'R', and VGA signals. The 35-MHz filter is useful for HDTV 720p/1080i Y'P'_BP'_R, G'B'R', and SVGA/XGA signals. For 1080p or SXGA/UXGA signals, the filter can be bypassed allowing a 150-MHz bandwidth, 300-V/µs amplifier to buffer the signal.
