Product details
Overview
THS7364IPWR from Texas Instruments is a 6-channel video amplifier IC with three SDTV (9.5-MHz LPF) and three Full-HD (72-MHz LPF) channels, 6-dB fixed gain, rail-to-rail output, and independent bypass/disable control per channel group-designed for set-top box, Blu-ray player, and PVR video output buffering.
For engineers reviewing the THS7364IPWR datasheet, THS7364IPWR pinout, THS7364IPWR application, or THS7364IPWR equivalent, key selection considerations include SD/FHD filter bandwidths, sync-tip clamp support for CVBS/Y', 75-Ω driving capability, low differential gain/phase (0.25%/0.4°), and TSSOP-20 package compatibility with space-constrained video signal chains.
Technical Context
The THS7364IPWR integrates six independent SiGe BiCom3X amplifier channels: three SD channels (CVBS/S-Video Y'/C') with fixed 9.5-MHz sixth-order Butterworth filters and three FHD channels (Y'/P'B'/P'R') with fixed 72-MHz sixth-order filters. Each channel group features dedicated bypass and disable logic inputs (Bypass SD/FHD, Disable SD/FHD).
It supports both AC-coupled (with sync-tip clamp for CVBS/Y'/G'B'R') and DC-coupled operation, delivers rail-to-rail output swing within 100 mV of rails, and maintains <0.3 ns channel-to-channel delay across all six channels-enabling precise timing alignment in multi-format video systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply voltage | +2.7 V to +5 V single supply - enables direct integration into 3.3-V or 5-V video subsystems without level-shifting. |
| SD channel bandwidth | 9.5 MHz (–3 dB, filter mode) - matches NTSC/PAL CVBS and S-Video Y'/C' baseband requirements. |
| FHD channel bandwidth | 72 MHz (–3 dB, filter mode) - supports 1080p60 Y'P'B'P'R' and computer RGB signals without aliasing. |
| Differential gain/phase | 0.25% / 0.4° (NTSC) - preserves color fidelity in broadcast-quality SD video paths. |
| Total quiescent current | 23.4 mA at 3.3 V (all channels active) - meets Energy Star® power budgets for consumer video equipment. |
| Output drive capability | Drives two 75-Ω loads per channel - allows fan-out to dual displays or recording + monitoring paths. |
| Disable supply current | 0.1 mA (all channels disabled) - enables dynamic power gating during inactive video modes. |
Pinout & Package
TSSOP-20 package (PW), RoHS-compliant, green, lead-free; 6.5 mm × 4.4 mm footprint with 0.65 mm pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| SD1 IN – SD3 IN (Pins 1–3) | SD video input channels | Accept CVBS, S-Video Y', or S-Video C'; each routed through internal 9.5-MHz LPF and 6-dB gain stage. |
| FHD1 IN – FHD3 IN (Pins 7–9) | FHD video input channels | Accept Y', P'B', P'R' or RGB; each routed through internal 72-MHz LPF and 6-dB gain stage. |
| Bypass SD / Bypass FHD (Pins 10, 11) | Filter bypass control | Logic high disables respective LPF, enabling full-bandwidth pass-through (e.g., for ADC/DAC reconstruction). |
| Disable SD / Disable FHD (Pins 17, 15) | Channel group enable/disable | Logic high disables all outputs in the group; reduces supply current to ≤0.1 mA per disabled group. |
| SD1 OUT – SD3 OUT (Pins 20–18) | SD video output channels | Rail-to-rail buffered outputs; support AC- or DC-coupled 75-Ω termination with 100-mV headroom. |
| FHD1 OUT – FHD3 OUT (Pins 14–12) | FHD video output channels | Same rail-to-rail output architecture as SD outputs; optimized for 72-MHz small-signal bandwidth and 500-V/µs slew rate. |
| VS+ (Pin 5), GND (Pin 16) | Power supply | Single 2.7–5-V supply; decoupling required at VS+ to maintain 70-dB SNR and low crosstalk. |
Key Features
| Feature | Design Value |
|---|---|
| Independent SD/FHD filter bypass | Enables system-level flexibility: use LPF for DAC reconstruction or bypass for ADC anti-aliasing without hardware change. |
| Sync-tip clamp on SD inputs | Restores DC level for CVBS/Y' signals in AC-coupled designs-eliminates external clamping diodes and bias networks. |
| Rail-to-rail output stage | Swings within 100 mV of VS+ and GND-supports both AC-coupled (capacitor + 75-Ω) and DC-coupled (75-Ω to mid-rail) video line driving. |
| Low inter-channel crosstalk | –72 dB (SD-to-SD @ 1 MHz), –70 dB (SD-to-FHD @ 25 MHz)-preserves signal integrity in mixed-resolution video routing. |
| 6-dB fixed gain (2×) | Compensates for typical DAC output attenuation and cable loss while maintaining unity-gain stability across all channels. |
Applications
| Set-Top Box Video Output | Blu-ray Player Analog Output |

IC Role / Device Role / Timing Role: Six-channel buffer with format-specific filtering: SD channels condition CVBS/S-Video; FHD channels condition 1080p component video. Use Value: Eliminates need for discrete op-amps and external filters-reduces BOM count by ≥6 components and PCB area by >30 mm². |
Use Scenario: Buffering high-fidelity Y'P'B'P'R' outputs from a BD-ROM video decoder to legacy AV receivers with analog inputs. IC Role / Device Role / Timing Role: Full-HD channel group provides 72-MHz bandwidth and <0.5° differential phase to preserve color accuracy and edge sharpness. Use Value: Meets SMPTE 293M timing jitter and ITU-R BT.709 color fidelity requirements without external tuning. |
| PVR/DVR Recording Output | Multi-Format Video Switcher |
Use Scenario: Simultaneously feeding live TV (CVBS) and recorded HD content (Y'P'B'P'R') to dual outputs: one for display, one for recording. IC Role / Device Role / Timing Role: Independent SD/FHD disable controls allow dynamic channel grouping-e.g., disable FHD during SD-only playback to cut power by 16.5 mA. Use Value: Enables adaptive power management compliant with Energy Star® 7.0 standby power limits (<0.5 W). |
Use Scenario: Routing mixed-source video (SD camera feed + HD graphics overlay) to a single analog monitor with selectable resolution. IC Role / Device Role / Timing Role: Bypass SD/FHD filters independently to pass baseband RGB from PC graphics or clean CVBS from security cam without LPF-induced group delay. Use Value: <0.3 ns channel-to-channel delay ensures pixel-perfect alignment between SD and HD layers in overlay compositing. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar video buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| THS7353IPW | 3-channel SD-only amplifier (9.5-MHz LPF), no FHD channels or bypass logic; 14-pin TSSOP. | Suitable only for SD-only systems (e.g., legacy DVD players); lacks Full-HD support and independent bypass control. | Select when cost and channel count are constrained and Full-HD output is not required. |
| LMH0387SQ/NOPB | 3G-SDI reclocking serializer with integrated equalizer; operates at 2.97 Gbps; requires 2.5-V supply. | Designed for serial digital video (SDI), not analog baseband; incompatible pinout and signal chain architecture. | Choose only for digital video transport; not a functional or drop-in replacement for analog video buffering. |
Compared with THS7364IPWR, THS7353IPW offers lower cost and power for SD-only use but omits FHD capability and bypass flexibility, while LMH0387SQ/NOPB serves a fundamentally different (digital serial) domain and cannot replace analog baseband amplification.

FAQ
What video standards does the THS7364IPWR support?
The THS7364IPWR supports NTSC/PAL CVBS, S-Video (Y'/C'), and Full-HD component formats including Y'P'B'P'R' up to 1080p60. Its SD channels meet SMPTE 170M and ITU-R BT.601 timing; FHD channels comply with ITU-R BT.709 bandwidth and group delay specs. THS7364IPWR does not process digital video protocols like HDMI or SDI.
Can the THS7364IPWR drive 75-Ω loads directly?
Yes, the THS7364IPWR is explicitly designed to drive dual 75-Ω loads per channel. Its rail-to-rail output stage delivers ≥3 VPP into 75 Ω at 3.3 V supply, with output impedance of 0.9 Ω (SD) or 9 Ω (FHD) at respective cutoff frequencies-ensuring proper termination and minimal signal reflection in broadcast video lines.
How does the sync-tip clamp function work on THS7364IPWR SD inputs?
The THS7364IPWR implements a transparent sync-tip clamp on SD inputs (Pins 1–3) for CVBS and Y' signals. When enabled via AC-coupled configuration, it restores DC level using internal current sources-eliminating need for external diodes, resistors, or capacitors. Clamp charge current is 140–200 mA at –0.1 V input, ensuring fast settling for field-rate video.
What is the purpose of the Bypass SD and Bypass FHD pins on the THS7364IPWR?
Bypass SD (Pin 10) and Bypass FHD (Pin 11) disable the internal sixth-order Butterworth LPFs for their respective channel groups. Logic high engages bypass mode-extending bandwidth to 150 MHz (SD) or 350 MHz (FHD)-for applications like DAC reconstruction or ADC anti-aliasing where full analog bandwidth is required. THS7364IPWR retains 6-dB gain and rail-to-rail drive in bypass mode.
Is the THS7364IPWR compatible with both 3.3-V and 5-V supplies?
Yes, THS7364IPWR operates over a +2.7-V to +5-V single supply range. Electrical performance-including 9.5-MHz SD bandwidth, 72-MHz FHD bandwidth, 0.25%/0.4° differential gain/phase, and 23.4-mA quiescent current-is fully specified and tested at both 3.3 V and 5 V. Logic thresholds scale with supply, supporting direct interface to 3.3-V or 5-V controllers.
