TVP5147M1PFPR 概要
What is a video decoder? A video decoder is a type of interface IC that converts analog baseband video signals (composite CVBS, Y/C, or YPbPr component) into digital ITU-R BT.656 or BT.601 video streams. Within the broader taxonomy, video decoders belong to encoders/decoders/converters in interface ICs, sitting between analog video sources (tuners, cameras, DVD players) and digital video processors (DSPs, SoCs, FPGAs). They are essential building blocks in LCD TV/Monitor designs where legacy analog video must be displayed on digital panels.
The TVP5147M1's key differentiating features include a hardware Macrovision detection circuit (Macrovision 1.x and 2.x compliant), a 5-line adaptive comb filter for superior luminance/chrominance separation in NTSC/PAL, automatic gain control with peak/average modes, and TI's proprietary chroma transient improvement (CTI) and luminance peaking circuitry. The device supports ten analog input channels selected via I2C, programmable H/V sync outputs, VBI data slicing for teletext/closed caption, and outputs ITU-R BT.656, BT.601, or raw VBI data over an 8- or 16-bit parallel interface. A single 27 MHz reference clock serves all standard video formats.
Architecturally, the TVP5147M1 combines two 10-bit, 30 MSPS ADCs with a programmable automatic gain control, a chroma demodulator with subcarrier PLL, a 5-line comb filter, and a digital output formatter. Analog supplies are 1.8 V (analog) and 3.3 V (I/O), while the digital core runs from an internally regulated 1.8 V supply. The HTQFP-80 PowerPAD package provides a thermal pad that must be soldered to a ground plane for adequate heat dissipation; PowerPAD operation lowers junction temperature and improves long-term reliability in always-on consumer equipment.
Typical applications include LCD TV and LCD monitor analog video inputs, set-top boxes archiving analog broadcasts, digital video recorders (DVR), video capture cards for PCs, in-car rear-seat entertainment displays, and security DVR systems. The Macrovision detection makes it suitable for licensed playback equipment where copy protection circuitry is mandated by content owners.
When designing with this device, ensure the PowerPAD is soldered to a continuous ground copper pour with multiple thermal vias to maximize heat flow. Use a 27 MHz crystal with low jitter (<50 ps RMS) to minimize pixel-clock jitter on the digital output, which directly impacts downstream display quality. Decouple the 1.8 V analog and 3.3 V I/O rails with 0.1 uF and 10 uF ceramic capacitors placed as close to the supply pins as practical.

主な用途
TVP5147M1PFPR の用途: 6 件s: LCD TV Analog Video Input, LCD Monitor Multi-Input Decoder, Digital Video Recorder (DVR) Capture, Set-Top Box Analog Passthrough, PC Video Capture Card, Automotive Rear-Seat Entertainment Display.
LCD TV Analog Video Input
The TVP5147M1PFPR serves as the primary analog front-end in LCD TV chassis that must accept legacy NTSC/PAL/SECAM broadcasts from RF tuners, composite video from VCRs, and component YPbPr from DVD players. Its dual 10-bit 30 MSPS ADCs and 5-line adaptive comb filter deliver clean YCbCr 4:2:2 video to the scaler/SOC, while the Macrovision detection enables legal playback of copy-protected commercial DVDs and broadcasts. Ten programmable input channels let the chassis designer route multiple sources through a single decoder IC, reducing BOM cost and PCB area. The HTQFP-80 PowerPAD package provides adequate thermal dissipation for continuous operation at 70 C ambient in an enclosed TV chassis, and the parallel BT.656 output interfaces seamlessly to mainstream video processors like the TVP5160 or DM644x.
おすすめ
LCD Monitor Multi-Input Decoder
Computer LCD monitors that need to accept analog VGA-style component video inputs (YPbPr from set-top boxes, gaming consoles) alongside composite CVBS from legacy equipment use the TVP5147M1PFPR as a universal decoder. The device's ten input channels map cleanly to monitor panel input matrices (Component1, Component2, CVBS1, CVBS2, S-Video). Its BT.601 16-bit parallel output delivers full 720x480i or 720x576i resolution, allowing the monitor's scaler to upconvert to the native panel resolution without quality loss. Macrovision detection is required for monitors displaying protected DVD or broadcast content. The PowerPAD thermal pad is critical here because monitors typically run in fan-less sealed enclosures; the exposed pad soldered to a 1 square-inch copper pour keeps junction temperature within the 0-70 C commercial range at full channel-load operation.
おすすめ
Digital Video Recorder (DVR) Capture
Surveillance and broadcast DVR systems digitize analog camera or broadcast feeds for MPEG-4/H.264 compression, and the TVP5147M1PFPR is a popular choice for the capture front-end. Its 10-bit resolution preserves dynamic range in noisy surveillance footage, and the 5-line comb filter improves chroma separation in low-quality broadcast captures. VBI data slicing extracts closed-caption text and teletext for archival metadata. The I2C interface allows multiple TVP5147M1 devices on the same bus, enabling multi-channel DVR cards with 4, 8, or 16 simultaneous capture channels. Power dissipation in always-on DVR equipment is moderate (~700 mW typical); the PowerPAD ground plane design must include a minimum 4 thermal vias (0.3 mm drill, 1 oz copper) to keep junction temperature below the 70 C commercial limit under continuous multi-channel encoding.
おすすめ
Set-Top Box Analog Passthrough
Cable and satellite set-top boxes that include analog passthrough outputs (for legacy TVs without HDMI) use the TVP5147M1PFPR to encode YPbPr output from decoded MPEG streams, or to decode incoming analog signals for internal processing. The ten input channels handle composite, S-Video, and component inputs simultaneously. Macrovision 1.x/2.x detection is essential for VCR/DVD passthrough paths where content owners require proof of copy protection. The HTQFP-80 package footprint is identical to the TVP5147M1's predecessor TVP5146, allowing existing STB designs to upgrade with Macrovision support without PCB rework. I2C programming enables automatic input format detection, simplifying the consumer-facing UI by eliminating manual video-standard selection.
おすすめ
PC Video Capture Card
Internal and external PC video capture cards (PCIe, USB, ExpressCard) use the TVP5147M1PFPR as the analog front-end for digitizing VHS tapes, legacy camcorder footage, and broadcast video. The 10-bit resolution outperforms 8-bit capture cards in color depth and SNR, which is critical for archival-quality digitization. VBI data slicing extracts closed-caption and teletext into text streams that the host software can index. The 5-line comb filter reduces cross-chroma artifacts in VHS and broadcast sources. Multiple TVP5147M1 devices on the same I2C bus enable 4-channel capture cards common in streaming/recording setups. Designers should isolate the analog ground plane from the digital ground using a ferrite bead at the PowerPAD connection to minimize digital switching noise coupling into the sensitive analog front-end.
おすすめ
Automotive Rear-Seat Entertainment Display
In-vehicle rear-seat entertainment (RSE) displays that accept analog video from DVD players, gaming consoles, or legacy media devices use the TVP5147M1PFPR as the decoder. Although the part's commercial 0-70 C temperature range limits use in the cabin head unit, RSE displays mounted in seat backs typically operate in the controlled cabin environment where ambient stays within commercial limits. The device's robust input channel selection accommodates DVD players, A/V input jacks, and game consoles simultaneously. Macrovision detection enables licensed DVD playback. Designers should add external ESD protection (TVS diodes) on analog inputs because automotive environments present ESD risks from passenger contact. The HTQFP-80 PowerPAD package is robust to vibration when properly soldered, meeting automotive vibration requirements for seat-mounted electronics.

設計ノート
Estimated: at typical 700 mW dissipation and 1 square-inch PowerPAD copper pour (4 thermal vias), the junction temperature rise above 25 C ambient is approximately 35 C, putting Tj near 60 C - well within the 70 C commercial limit. In sealed enclosures without airflow, increase copper area to 2 square inches or add a small heatsink attached to the PowerPAD.
Solder the PowerPAD (thermal pad) on the underside of the HTQFP-80 directly to a continuous ground copper pour with a minimum of 4 thermal vias (0.3 mm drill, 1 oz copper plated to 0.5 oz in barrel). Per TI's application note, this layout is mandatory for rated thermal performance; failure to solder the PowerPAD voids the datasheet thermal specifications.
Use a 27 MHz crystal with phase jitter below 50 ps RMS; jitter on the reference clock directly couples to the pixel clock output, causing horizontal-line pixel-jitter visible on the display. Place the crystal within 5 mm of XTAL1/XTAL2 pins and isolate the crystal traces with a guard ground ring. A series resistor (10-33 ohm) in XTAL1 can dampen overdrive but is not always required.
Decouple the 1.8 V analog (AVDD1.8) and 3.3 V I/O (DVDD3.3) rails separately with 0.1 uF and 10 uF ceramic capacitors placed within 3 mm of the supply pins. Do not share decoupling capacitors between analog and digital supplies - the common-mode noise from the digital core will couple into the sensitive analog ADC and degrade SNR. Use a ferrite bead between AVDD and DVDD planes if they share a single regulator.
Route analog input traces (AIP1A-AIP6A) as 75-ohm impedance-matched differential pairs with a continuous ground reference plane underneath. Keep digital output traces (D[15:0], HSYNC, VSYNC, PCLK) at least 3 mm away from analog input traces to prevent digital switching noise coupling into the analog front-end. The TI datasheet reference layout shows this 4-layer stackup: signal/component/GND/power.
