Schmitt Trigger • RoHS TQFP Package • 2:1 Input MUX • I2C™ Control of All Functions • Projectors • Integrated Low-Pass Filters on ADC Buffers • Professional Video Systems – 5th Order Butterworth Characteristics • LCD/DLP/LOCS Input Buffering – Selectable Corner Frequencies of 9-MHz, 16-MHz, 35-MHz, and 75-MHz with Bypass (500-MHz) Fabricated using the new complimentary • Selectable Input Bias Modes silicon-germanium (SiGe) BiCom-III process, the – AC-Coupled with Sync-Tip Clamp THS7327 is a low-power, single-supply 2.7-V to 5-V, 3-channel integrated video buffer with H and V Sync – AC-Coupled with Bias signal paths. It incorporates a selectable 5th order – DC-Coupled with Offset Shift Butterworth anti-aliasing filter on each channel. The – DC-Coupled 9-MHz is a perfect choice for SDTV video including composite, S-Video™, and 480i/576i. The 16-MHz • Monitor Pass-Thru Function: filter is ideal for EDTV 480p/576p, and VGA signals. – Passes the Input Signal With no Filtering The 35-MHz filter is useful for HDTV 720p/1080i, and – 500-MHz BW and 1300 V/ µs Slew Rate SVGA signals. The 75-MHz filter is ideal for HDTV – 6-dB Gain With SAG Correction Capable 1080p and XGA/SXGA signals. For UXGA/QXGA R’G’B’ signals, the filter can be bypassed allowing a – High Output Impedance in Disable State 500-MHz bandwidth, 1150-V/ µs amplifier to buffer • 2.7-V to 5-V Single Supply Operation the signal. • Low 330 mW at 3.3-V Power Consumption • Disable Function Reduces Current to <1 µA Figure 1. 3.3 V Single-Supply AC-Input/AC-Video Output System w/SAG Correction (1 of 3 Channels Shown) Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.
