TVP5150AM1PBS 概要
A video decoder is an integrated circuit that captures analog composite or S-Video signals and converts them into a digitized component video stream for downstream processing by application processors, SoCs, or display controllers. The device category hierarchy is: video decoder -> analog front-end -> interface IC -> semiconductor. Its role in a typical embedded vision system is to bridge analog cameras or legacy analog video sources (CVBS, Y/C) to modern digital processing pipelines, eliminating the need for external ADCs and sync separators while preserving signal integrity.
Key features include a high-speed 9-bit ADC, fully differential CMOS analog preprocessing with AGC and clamping for best signal-to-noise performance, complementary 4-line adaptive comb filtering on both luminance and chrominance paths, Macrovision copy-protection support, and an ultralow-power architecture suited to portable designs. A Genlock/real-time control (RTC) output is generated for synchronizing downstream video encoders in multi-camera or PIP architectures.
Technically, the TVP5150AM1 uses a differential analog front end that rejects common-mode noise and supports extended temperature operation from 0°C to 70°C in the PBS package variant. Its register-based I²C control interface exposes luminance, chrominance, hue, brightness, contrast, and sharpness adjustments to the host processor.
Typical applications include portable media players, set-top boxes, digital video recorders, video capture cards, automotive infotainment rear-seat entertainment, IP cameras with analog CVBS input, and surveillance DVRs. The wide standard coverage and ultralow-power operation make it suitable for any embedded design that must decode legacy analog video.
When designing with this part, pay attention to the I/O supply sequencing constraint: IO_DVDD must track the 1.8 V digital supply and must not be back-powered; an external power-on-reset (POR) or supply sequencing network may be required for multi-supply rails. Place the 27 MHz crystal or clock source within 5 mm of the XTAL pin and use a star-ground topology for the CVBS traces.

主な用途
TVP5150AM1PBS の用途: 6 件s: Portable Media Player Analog Video Input, Set-Top Box Analog CVBS Capture, Video Capture Card / PCIe DVR Board, Surveillance DVR / IP Camera with CVBS Output, Digital Video Recorder / Streaming Encoder, Automotive Infotainment CVBS Input.
Portable Media Player Analog Video Input
The TVP5150AM1PBS fits portable media player designs because its ultralow ~110 mW power draw and 32-pin TQFP-32 (5x5 mm) package fit within battery and PCB real-estate budgets while decoding composite or S-Video at 27 MHz ITU-R BT.656. Its 9-bit ADC captures NTSC, PAL, and SECAM with sufficient chroma resolution for playback on a 3 to 5-inch LCD, and the 4-line adaptive comb filter preserves chroma bandwidth at low input signal amplitudes typical of consumer camcorder output.
おすすめ
Set-Top Box Analog CVBS Capture
The TVP5150AM1PBS enables set-top boxes and hybrid IPTV gateways to ingest CVBS baseband from legacy cable plant or analog RF demodulator outputs. Its NTSC/PAL/SECAM auto-detection means a single hardware SKU handles worldwide deployments, and the discrete sync output mode (selectable via I²C) interfaces with MPEG-2/H.264 encoder SoCs lacking a native BT.656 port. Genlock/RTC output synchronizes downstream HDMI encoders without additional PLLs.
おすすめ
Video Capture Card / PCIe DVR Board
The TVP5150AM1PBS is widely deployed in multi-channel video capture cards and PCIe DVR boards where four or more units operate in parallel to capture up to 16 CVBS channels. Its ultralow power reduces total board thermal load, while the robust sync detector locks onto degraded VCR tapes and noisy CCTV feeds. Combined with an FPGA or SoC that aggregates multiple BT.656 streams over 27 MHz pixel clocks, it forms a high-density multi-channel capture front end.
おすすめ
Surveillance DVR / IP Camera with CVBS Output
The TVP5150AM1PBS converts analog CVBS camera signals to digital BT.656 inside DVRs and hybrid IP cameras that retain a CVBS service-monitor output. Its Macrovision detection supports rental-VCR playback in hospitality DVRs, while the 9-bit ADC provides sufficient dynamic range for shadow detail in low-light CCTV footage. The 32-pin TQFP footprint allows compact 4-channel DVR boards where each decoder occupies ~5x5 mm of PCB.
おすすめ
Digital Video Recorder / Streaming Encoder
The TVP5150AM1PBS serves as the front-end decoder in HDMI/USB capture dongles that record VHS or legacy analog sources to modern digital storage. Its ITU-R BT.656 output streams 8-bit YCbCr 4:2:2 at 27 MHz, which the host SoC encodes to H.264/H.265 in real time. The small 32-pin TQFP package and 1.8 V supplies are compatible with space-constrained dongle form factors and USB-powered operation.
おすすめ
Automotive Infotainment CVBS Input
The TVP5150AM1PBS is used in non-automotive-qualified rear-seat entertainment and aftermarket infotainment systems that accept CVBS from a backup camera or external media player. The robust sync detector handles the noisy EMI environment near a vehicle's ECU, while the 4-line adaptive comb filter prevents cross-luminance artifacts in composite video. For OEM automotive (AEC-Q100) applications, designers should select TI's AEC-Q100-qualified TVP5150-family variant instead.

設計ノート
Power sequencing is mandatory: IO_DVDD (1.65 V to 3.6 V) must be applied before or simultaneously with DVDD (1.65 V to 1.95 V) to prevent I/O latch-up. A 10 kΩ pull-down on RESET# holds the decoder in reset until all supplies are stable. Use a low-noise LDO (e.g., TPS7A4701 or TPS7A4533) to keep AVDD ripple below 10 mVpp for best signal-to-noise ratio; switching regulators directly on AVDD will inject switching noise into the analog front-end.
Place the 27 MHz crystal within 5 mm of pins 15/16 (XI/XO) and use a star-ground topology tying analog ground (pin 7) and digital ground (pin 13) together only at the device's thermal pad. Add 0.1 µF and 10 µF ceramic bypass caps on each AVDD/DVDD pin. Route the 8-bit YOUT[7:0] bus with matched trace lengths (≤ 25 mm) and a 50 Ω characteristic impedance over a continuous ground plane; impedance mismatch causes data-dependent jitter visible as colored noise on analog video output.
Series-terminate each YOUT[7:0] trace with 33 Ω near the TVP5150AM1PBS to dampen ringing into capacitive loads on the host SoC. Keep CVBS traces routed as 75 Ω controlled-impedance lines and use an active clamp circuit (per TI TVP5150AM1 reference schematic) to protect the analog inputs from cable ESD. Add a 75 Ω back-termination resistor at each CVBS input for proper video signal amplitude.
Do not apply power to DVDD before IO_DVDD - this violates the supply sequencing requirement and may permanently latch the I/O buffers. Avoid back-powering IO_DVDD from the host SoC's I/O rail before the TVP5150AM1's DVDD is stable; an external power-OR with a Schottky diode is recommended for hot-plug-safe host interfaces. Estimated power dissipation in typical operation: AVDD 45 mA × 1.8 V ≈ 81 mW plus DVDD 28 mA × 1.8 V ≈ 50 mW plus IO_DVDD load-dependent ≈ 110 mW total.
