TVP5150AM1IPBS 概要
What is a video decoder? A video decoder is a mixed-signal integrated circuit that digitizes analog broadcast video (NTSC, PAL, SECAM) and reformats it into a standard digital stream that downstream processors, image signal processors (ISPs), or video encoders can consume. In the broader taxonomy, the TVP5150AM1IPBS sits under video front-end ICs -> interface ICs -> integrated circuits, and historically it dominated mobile, surveillance, and set-top box designs where small footprint and low power were non-negotiable.
Key features include a robust sync detector for non-standard and weak signals, Genlock/real-time control (RTC) output for synchronizing downstream encoders, complementary 4-line adaptive comb filtering for both luminance and chrominance paths, and a programmable chrominance trap filter. Per the TI datasheet, power consumption is typically below 150 mW, and the device operates from a 1.8 V core supply with a 3.3 V I/O supply via an integrated level shifter.
Technically, the device uses a 9-bit pipelined ADC architecture, two fully differential analog preprocessing channels, and an on-chip PLL to generate the 27 MHz sampling clock from a 27 MHz crystal or external reference. The I2C interface is used for configuration of video standard, brightness, contrast, saturation, hue, and comb-filter enable, while the parallel 8-bit output uses the ITU-R BT.601 or BT.656 interface standard.
Typical applications include handheld/personal video recorders, mobile phone video capture, portable media players, digital still cameras, automotive infotainment rear-seat displays, and CCTV/DVR surveillance front ends where composite CVBS must be digitized for compression ASICs or SoCs.
When designing with this device, provide adequate bulk decoupling on both the 1.8 V (DVDD) and 3.3 V (IO_DVDD) rails and route the analog video inputs with controlled 75 ohm impedance to minimize reflections. The S-Video Y/C pair is preferred over CVBS for best comb-filter performance.

主な用途
TVP5150AM1IPBS の用途: 6 件s: Portable Video Recorder / Camcorder Front End, Mobile Phone Video Capture Accessory, Digital Still Camera Video Preview, Automotive Rear-Seat Infotainment / Headrest Display, CCTV / DVR / Surveillance Front End, Industrial Video Inspection / Machine Vision Front End.
Portable Video Recorder / Camcorder Front End
The TVP5150AM1IPBS fits handheld camcorder and pocket DVR designs because it digitizes composite or S-Video from a single CCD/lens module into ITU-R BT.656 with typically under 150 mW the ADC core draws only 1.8 V, so battery-powered designs can run for hours from a single lithium cell. Per the TI datasheet, the 32-pin TQFP (PBS) 5x5 mm footprint keeps the BOM compact, and the I2C host control integrates cleanly into the main SoC bus. Designers commonly pair it with a downstream H.264 encoder ASIC. Compared to a TVP5154 (4-channel), the TVP5150AM1IPBS is single-channel and thus better suited to consumer capture than multi-camera security applications.
おすすめ
Mobile Phone Video Capture Accessory
The TVP5150AM1IPBS is well matched to mobile phone video capture dongles, TV-OUT capture sticks, and pico-projector accessories. Its 1.65 V to 1.95 V DVDD supply rail interfaces directly to cell-phone PMIC outputs, while the 1.65 V to 3.6 V IO_DVDD range connects to 1.8 V or 3.3 V application processors without level shifters. Per TI datasheet robustness specs, the analog front end tolerates the noisy switching rails typical in cellular platforms. The robust sync detector also handles weak or non-standard analog sources such as set-top boxes and legacy camcorders, ensuring plug-and-play interoperability for consumer accessories.
おすすめ
Digital Still Camera Video Preview
The TVP5150AM1IPBS supports digital still cameras that must preview analog video on the rear LCD while capturing stills. Its ITU-R BT.656 8-bit parallel output streams into an ISP or SoC that overlays graphics and exposes menus. Per the TI TVP5150AM1 datasheet, the adaptive 4-line comb filter reduces cross-luminance and cross-chrominance artifacts in the preview path. With typically less than 150 mW dissipation and a 5x5 mm TQFP footprint, it integrates well into compact DSCs where PCB area is constrained and the 27 MHz sampling reference can be sourced from the SoC's master clock tree.
おすすめ
Automotive Rear-Seat Infotainment / Headrest Display
The TVP5150AM1IPBS handles analog video inputs in automotive rear-seat entertainment, where composite CVBS from a DVD player or set-top box feeds headrest or seatback displays. Per TI datasheet, the device's industrial -40 C to +85 C temperature grade tolerates cabin thermal swings, and the robust sync detector prevents rolling or tearing when the source VCR/DVD output drifts. The Genlock output can synchronize downstream video encoders for multi-display architectures. Note that for new automotive designs TI recommends qualifying the successor TVP5151IPBSR or a newer AEC-Q100 part; the TVP5150AM1IPBS is suitable for industrial-spec rear-seat designs but is NRND overall.
おすすめ
CCTV / DVR / Surveillance Front End
The TVP5150AM1IPBS digitizes CVBS inputs in single-channel CCTV camera nodes and DVR capture cards. Its two CVBS channels support dual-camera front ends without an external mux, and the robust sync detector handles the degraded video typical of long cable runs. Per the TI datasheet, complementary 4-line adaptive comb filtering improves luma/chroma separation on noisy analog feeds, sharpening forensic detail. Designers typically cascade the BT.656 stream into a downstream H.264/MJPEG encoder ASIC or SoC. For multi-channel DVR capture cards with 4+ cameras the TVP5154PNP is a better fit since the TVP5150AM1IPBS is limited to two composite inputs.
おすすめ
Industrial Video Inspection / Machine Vision Front End
The TVP5150AM1IPBS is suited to industrial video inspection equipment where legacy analog cameras must be interfaced to modern digital SoCs. Its two CVBS inputs support dual-camera borescopes or endoscope front ends, and the industrial -40 C to +85 C temperature range tolerates factory-floor thermal environments. Per TI datasheet electrical characteristics, the differential analog preprocessing delivers high SNR even with long cable runs in EMI-rich environments. The I2C-controlled brightness, contrast, saturation, and hue registers allow software tuning for different lighting conditions without hardware rework.

設計ノート
Estimated: The TVP5150AM1IPBS draws typically <150 mW total, broken into DVDD (1.8 V core), IO_DVDD (3.3 V I/O), AVDD (1.8 V analog), and PLL_AVDD (1.8 V PLL). Per the TI datasheet, place a 0.1 uF decoupling capacitor within 5 mm of each supply pin and a 10 uF bulk capacitor on each rail. Star-ground the analog and digital grounds at a single point near the IC to minimize switching-noise coupling into the analog front end. The IO_DVDD rail can be tied to 3.3 V to directly drive 3.3 V SoCs without level shifters.
Route the two analog video inputs (AIP1A, AIP1B) with 75 ohm controlled-impedance traces terminated to ground at the IC side. Per the TI datasheet application notes, place a 75 ohm termination resistor and an AC-coupling 0.1 uF capacitor in series on each analog input. Keep analog traces away from digital switching signals (YOUT[7:0], PCLK) and from noisy supplies to preserve SNR. Use a solid ground pour under the analog section, with stitching vias every lambda/20 around the analog input area.
Common pitfalls when designing with the TVP5150AM1IPBS include (1) forgetting the 27 MHz crystal load capacitor values - per TI datasheet, use 18 pF for typical crystals; (2) leaving the RESETB pin floating - it must be pulled high after power-up with a 10 kohm resistor; (3) misconfiguring the I2C slave address - the default is 0xB8 (write) / 0xB9 (read); (4) expecting ITU-R BT.656 output without setting the OFMT bit - default is BT.601 mode; and (5) omitting input clamping - the on-chip clamping requires the inputs to be DC-biased via the external AC-coupling network.
