THS7353PW General Description

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.

Each channel of the THS7353 is individually I²C configurable for all functions which makes it flexible for any application. Its rail-to-rail output stage allows for both ac and dc coupling applications. The externally controlled gain adjust pin allows for fine tuning of the gain such as line driving, compensating for cable losses, or Sin-X/X compensation.

As part of the THS7353 flexibility, the 2:1 MUX input can be selected for ac or dc coupled inputs. The ac coupled modes include a sync-tip clamp option for CVBS/Y′/G′B′R′ with sync or a fixed bias for the C′/P′_B/P′_R channels. The dc input options include a dc input or a dc + 250-mV input offset shift to allow for a full sync dynamic range at the output with 0-V input.

The THS7353 is the perfect choice for all video buffer applications. The 16.2-mA total quiescent current (54 mW total power) makes it an excellent choice for USB powered or portable video applications. While fully disabled, the THS7353 consumes less than 1 µA.
