THS7316 www.ti.com SLOS521 – MARCH 2007 3-Channel HDTV Video Amplifier With 5th-Order Filters and 6-dB Gain FEATURES • • 3 HDTV Video Amplifiers for Y'P'BP'R 720p and 1080i, G'B'R' (R'G'B'), VGA/SVGA/XGA Integrated Low-Pass Filters – 5th-Order 36-MHz (–3 dB) Butterworth Filter – –1 dB Passband Bandwidth at 31 MHz – 30 dB Attenuation at 74 MHz Versatile Input Biasing – DC-Coupled With 140-mV Input Shift – AC-Coupled with Sync-Tip Clamp – Allows AC-Coupled With Biasing Built-in 6-dB Gain (2V/V) 3-V to 5-V Single Supply Operation Rail-to-Rail Output: – Output Swings Within 100 mV From the Rails Allowing AC or DC Output Coupling – Supports Driving 2 Lines per Channel Low 18.3-mA at 3.3-V Total Quiescent Current Low Differential Gain/Phase of 0.1% / 0.1° SOIC-8 Package DESCRIPTION Fabricated using the Silicon-Germanium (SiGe) BiCom-III process, the THS7316 is a low power single-supply 3-V to 5-V, 3-channel integrated video buffer. It incorporates a 5th-order modified Butterworth filter which is useful as a DAC reconstruction filter or an ADC anti-aliasing filter. The 36-MHz filter is a perfect choice for HDTV video which includes Y'P'BP'R 720p/1080i, G'B'R' (R'G'B'), and VGA/SVGA/XGA signals. As part of the THS7316 flexibility, the input can be configured for ac or dc coupled inputs. The DC + 140-mV input offset shift to allow for a full sync dynamic range at the output with 0-V input. The AC coupled modes include a transparent sync-tip clamp option for signals with sync such as Y’ or Green with sync. AC-coupled biasing for P’B/P’R/Non-sync channels can be achieved by adding an external resistor. The THS7316 is the perfect choice for all output buffer applications. Its rail-to-rail output stage with 6-dB gain allows for both ac and dc line driving. The ability to drive 2 video lines per channel, or 75-Ω loads, allows for maximum flexibility as a video line driver. The 18.3-mA total quiescent current makes it an excellent choice for USB powered, portable, or other power sensitive video applications. The THS7316 is available in a small SOIC-8 package that is RoHS compliant.

Copyright © 2007, Texas Instruments Incorporated THS7316 SLOS521 – MARCH 2007 www.ti.com This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with appropriate precautions. Failure to observe proper handling and installation procedures can cause damage. ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.

These are stress ratings only and functional operation of the device at these or any other conditions beyond those indicated under recommended operating conditions is not implied. Exposure to absolute maximum rated conditions for extended periods may degrade device reliability. The absolute maximum junction temperature under any condition is limited by the constraints of the silicon process. The absolute maximum junction temperature for continuous operation is limited by the package constraints. Operation above this temperature may result in reduced reliability and/or lifetime of the device. DISSIPATION RATINGS PACKAGE SOIC-8 (D) (1) (2) θJC (°C/W) 16.8 θJA (°C/W) 130 (2) POWER RATING (1) (TJ = 125°C) TA = 25°C 769 mW TA = 85°C 308 mW Power rating is determined with a junction temperature of 125°C. This is the point where performance starts to degrade and long-term reliability starts to be reduced. Thermal management of the final PCB should strive to keep the junction temperature at or below 125°C for best performance and reliability. This data was taken with the JEDEC High-K test PCB. For the JEDEC low-K test PCB, the θJA is 196°C/W.
