Texas Instruments THS7368IPWR

Overview

THS7368IPWR from Texas Instruments is a 6-channel single-supply video amplifier with three fixed 9.5-MHz SDTV filters and three selectable SD/ED/HD/Full-HD (9.5/18/36/72 MHz) low-pass filters, 6-dB gain, rail-to-rail output, and 23.4 mA quiescent current at 3.3 V - used in set-top box, PVR, and Blu-ray video output buffering.

For engineers reviewing the THS7368IPWR datasheet, THS7368IPWR pinout, THS7368IPWR application, or THS7368IPWR equivalent, this page delivers verified electrical specs, filter mode truth tables, input coupling options (DC-coupled with 300-mV shift or AC-coupled with sync-tip clamp), and real-world video line driving performance for CVBS, S-Video Y'/C', and component RGB/P'B'P'R' signals.

Technical Context

The THS7368IPWR integrates six independent video buffer channels: SD1–SD3 (CVBS/S-Video Y'/C') with fixed 9.5-MHz sixth-order Butterworth LPFs, and SF1–SF3 (Y'/P'B'/P'R' or RGB) with programmable filter selection via FILTER 1/FILTER 2/BYPASS SF logic inputs. Each channel provides 6-dB gain and rail-to-rail output swing within 100 mV of supply rails.

It supports dual input biasing modes: DC-coupled operation with internal 300-mV output level shift enabling full sync dynamic range from 0-V input, and AC-coupled operation with transparent sync-tip clamp for CVBS/Y'/G'B'R' or external resistor bias for C'/P'B'/P'R'. Disable SD/SF pins allow per-group channel shutdown to 0.1 μA.

FAQ

What video standards does the THS7368IPWR support?

The THS7368IPWR supports NTSC/PAL CVBS, S-Video (Y'/C'), and component video (Y'/P'B'/P'R' or RGB) across SD, ED, HD, and Full-HD resolutions. Its SD channels feature fixed 9.5-MHz filters for broadcast analog standards, while SF channels offer programmable 9.5/18/36/72-MHz filters or bypass mode - enabling compliance with 480i, 576i, 720p, 1080i, and 1080p signal bandwidths. THS7368IPWR maintains 0.2%/0.35° differential gain/phase for NTSC, ensuring broadcast-grade color fidelity.

How do I configure the THS7368IPWR for HD component video output?

To configure THS7368IPWR for HD component video (e.g., 720p Y'/P'B'/P'R'), connect SF1–SF3 inputs to the source, set FILTER 1 = HIGH, FILTER 2 = LOW, and BYPASS SF = LOW to select the 36-MHz HD filter. Ensure VS+ = 3.3 V or 5 V, disable SD channels if unused (DISABLE SD = HIGH), and terminate each SF output with 75 Ω to GND or +VS/2. THS7368IPWR delivers 6-dB gain, rail-to-rail swing, and <7.5 ns group delay variation at 27 MHz - preserving timing integrity for HD formats.

Can the THS7368IPWR drive two 75-Ω loads simultaneously per channel?

Yes, the THS7368IPWR rail-to-rail output stage is explicitly rated to drive two 75-Ω loads per channel - confirmed by TI's "Supports Driving Two Video Lines/Channel" feature and output swing specifications (e.g., 3.1 V high swing into 75 Ω at 3.3 V). This capability eliminates need for external splitters or buffers in dual-output designs (e.g., front-panel + rear-panel video jacks). THS7368IPWR maintains <0.2% differential gain error and >46 dB return loss at 6.75 MHz under this load condition.

What are the input coupling options for THS7368IPWR SD channels?

The THS7368IPWR SD channels support two verified input coupling modes: (1) DC-coupled with internal 300-mV output level shift - enabling full sync-tip-to-tip video swing from 0-V input, and (2) AC-coupled with transparent sync-tip clamp - automatically restoring DC level on CVBS, Y', or G'B'R' signals without external diodes or capacitors. THS7368IPWR's datasheet specifies clamp charge current (140–200 μA) and input voltage range (–0.1 V to +1.46 V at 3.3 V) for robust sync detection.

Does THS7368IPWR support power-down mode, and how much current does it draw?

Yes, THS7368IPWR supports hardware-controlled power-down via DISABLE SD and DISABLE SF pins. When both are driven HIGH, total supply current drops to 0.1 μA (typical) - verified across temperature and supply voltage (3.3 V and 5 V). This ultra-low disabled current enables dynamic power gating in energy-sensitive applications like portable media players or standby-mode set-top boxes. THS7368IPWR also features 100-ns enable/disable timing for rapid wake-up.
