APPLICATION INFORMATION
www.ti.com
The THS7376 is targeted for applications that require one standard-definition (SD) video output buffer for CVBS
video support along with three full high definition (HD) video output buffers. Although the video signal can be
used for numerous other applications, the needs and requirements of the video signal are the most important
design parameters of the THS7376. Built on the revolutionary, complementary Silicon Germanium (SiGe)
BiCom3X process, the THS7376 incorporates many features not typically found in integrated video devices while
consuming very low power. The THS7376 includes the following features:
• 3-V to 5-V, single-supply operation with a low total quiescent current of 30.9 mA at 3.3 V and 32.6 mA at 5 V.
• Disable mode enables shutting down the device to save system power in power-sensitive applications. This
mode reduces quiescent current to as low as 0.1 µA.
• Flexible input configurations accept dc + level shift, ac sync-tip clamp, or ac-bias. AC-biasing is configured by
using external pull-up resistors to the positive power supply.
• A low-pass filter for DAC reconstruction or ADC image rejection provides:
– A 6th-order, 10-MHz filter for NTSC, PAL, SECAM, and composite video (CVBS) baseband signals, and
– Three 8th-order, 42-MHz filters for 720p, 1080i, or up to 1080p30 Y’, P’_B, P’_R, or G’B’R’ signals. These
filters also support 480i and 576i or 480p and 576p component video signals.
• HD bypass mode bypasses the HD low-pass filters for all three channels. The HD channels can support a
1080p60 full-HD component video or SXGA RGB video with 300-MHz and 375-V/µs performance.
–
• Internally-fixed gain of 2-V/V (+6-dB).
• Supports driving two video lines per channel with dc-coupling or traditional ac-coupling.
• Robust 10-kV ESD protection on video output pins and 8-kV ESD protection on all other pins
• Flow-through configuration using a TSSOP-14 package that complies with the latest lead-free (RoHS-
compatible) and green manufacturing requirements.
• The THS7373 and THS7374 from TI are drop-in compatible devices.
