ADV7393BCPZ-REEL 概述
A video encoder is a data converter IC that translates digital video streams (parallel ITU-R BT.656 / BT.601, or serial HDMI-derived pixel data) into analog waveforms suitable for legacy displays, broadcast modulation, or recording onto analog media. Within the broader taxonomy it sits inside data converters (video DAC + encoder) and ultimately under interface/signal-chain ICs. The ADV7393 family targets applications that still require analog video outputs after SoC integration.
Key specifications include three 2.7 V/3.3 V 10-bit video DACs, support for SD (NTSC/PAL/SECAM) and HD (720p/1080i) timing standards, a low-power sleep pin, I²C control interface, and a wide operating temperature range suitable for consumer set-top boxes, DVD/BD recorders, and video capture cards. The part is specified across -40 °C to +85 °C ambient conditions.
Architecturally the device combines a digital encoder block (which inserts sync, blanking, and color modulation) with three current-steering DACs that drive the three analog outputs. Internal PLL-derived timing generation eliminates the need for an external pixel clock in many modes, simplifying board layout. The 40-LFCSP package and exposed thermal pad allow direct PCB thermal dissipation and short analog output traces, important at HD color bandwidths where trace impedance must be tightly controlled.
Typical applications include set-top box encoder outputs, DVD and Blu-ray player composite/component video, video capture cards, and industrial test pattern sources. The single 3.3 V rail makes it straightforward to retrofit onto existing 3.3 V designs without adding an LDO. The companion ADV7390/91/92 family members share the same digital architecture and register map, allowing firmware reuse across the encoder line.
When designing with this device, keep analog output traces matched to 75 ohm impedance with a 75 ohm termination at the load connector. Place decoupling capacitors immediately adjacent to AVDD and DVDD pins, and tie the exposed thermal pad to a clean analog ground plane. For HD formats, use the 2 x oversampling mode to ease analog filter requirements.

典型应用
ADV7393BCPZ-REEL 适用于 7 应用s: Set-Top Box Composite/Component Video Output, DVD and Blu-Ray Player Analog AV Outputs, Video Capture Card Composite/S-Video Input, Industrial Test Pattern and Calibration Generator, Digital Signage and Kiosk Analog Display Output, Automotive Infotainment (Non-Safety) Analog Video, Medical Imaging Display Interface (Legacy).
Set-Top Box Composite/Component Video Output
The ADV7393BCPZ-REEL fits set-top box designs because it integrates three 10-bit video DACs and supports both SD (NTSC/PAL/SECAM) and HD (720p/1080i) formats in a single chip. According to the ADI datasheet Rev. K, the part accepts parallel ITU-R BT.601/BT.656 digital video from a host SoC and emits CVBS, S-Video, and component YPrPb simultaneously. Its 2.7 V to 3.3 V supply aligns with typical STB power rails, removing extra regulators. The 40-LFCSP-VQ (6x6 mm) footprint fits behind the rear-panel RCA connectors without crowding the tuner section.
推荐
DVD and Blu-Ray Player Analog AV Outputs
The ADV7393BCPZ-REEL suits DVD/Blu-ray players that still need legacy analog outputs for older A/V receivers. Its three 10-bit DACs deliver composite, S-Video, and component simultaneously, so a single encoder handles all rear-panel jacks. According to ADI documentation, the part supports both NTSC and PAL disc content with on-the-fly format detection, simplifying firmware. The exposed thermal pad of the 40-LFCSP-VQ package provides sufficient heat dissipation at typical 3.3 V operating power for the consumer-electronics thermal budget.
推荐
Video Capture Card Composite/S-Video Input
The ADV7393BCPZ-REEL is used in PC video capture cards where the host application needs to convert analog video inputs to digital streams for recording or streaming. Its three 10-bit DACs are deployed as test-pattern generators for self-test and HDMI-handshake calibration. Per ADI documentation, the on-chip PLL-derived timing eliminates the need for an external pixel clock in many modes, reducing BOM cost. The 40-LFCSP-VQ (6x6 mm) footprint fits alongside USB3 or PCIe bridge ICs on typical 4-layer capture-card PCBs.
推荐
Industrial Test Pattern and Calibration Generator
The ADV7393BCPZ-REEL serves industrial video test equipment where stable analog reference signals calibrate downstream A/V analyzers. Its three 10-bit DACs produce precision color bars, ramps, and multipulse patterns per SMPTE/RP 219 with high linearity. According to ADI datasheet Rev. K, the wide operating temperature range of -40 °C to +85 °C supports factory-floor and outdoor cabinet installations. I²C control via a microcontroller allows remote pattern switching without manual intervention.
推荐
Digital Signage and Kiosk Analog Display Output
The ADV7393BCPZ-REEL is suitable for digital signage and kiosk controllers driving analog LCD panels or legacy projectors that lack digital inputs. Its HD 1080i component output preserves full resolution for large-format displays while composite/S-Video outputs handle backup or smaller secondary screens. According to ADI documentation, the single 3.3 V supply simplifies the kiosk power tree. The 40-LFCSP-VQ package's exposed pad allows direct PCB thermal dissipation in fanless kiosk enclosures.
推荐
Automotive Infotainment (Non-Safety) Analog Video
Although the ADV7393BCPZ-REEL is not AEC-Q100 qualified, it is used in non-safety automotive applications such as rear-seat entertainment and headrest displays where analog video distribution is still common. Its three 10-bit DACs feed multiple in-cabin monitors, and its wide temperature range handles cabin thermal swings. According to the ADI datasheet, designers should validate thermal performance at +85 °C ambient with the LFCSP exposed pad soldered to a sufficiently large copper pour. Automotive safety-critical displays require a different qualified encoder.
推荐
Medical Imaging Display Interface (Legacy)
The ADV7393BCPZ-REEL fits legacy medical imaging peripherals and review stations that distribute analog video to older diagnostic monitors. Its 10-bit resolution and clean DAC output provide adequate grayscale linearity for diagnostic review. According to ADI documentation, the encoder accepts parallel digital video from image-processing ASICs without requiring an external pixel clock. Designers must follow IEC 60601 separation and grounding guidelines and validate the specific medical system's compliance separately.

设计说明
Per ADI ADV7393 datasheet Rev. K, place 0.1 µF decoupling capacitors immediately adjacent to each AVDD and DVDD pin, with a bulk 10 µF tantalum or ceramic close to the package. The exposed thermal pad must be soldered to a clean analog ground pour with at least 8 thermal vias to inner layers for heat spreading. Keep analog output traces (DAC_A/B/C) matched to 75 ohm characteristic impedance with a 75 ohm termination resistor at the connector side for correct video levels.
Separate analog and digital ground planes with a single-point bridge under the IC. According to ADI reference layouts, route the I²C lines (SDA, SCL) away from the analog output traces to prevent digital noise coupling into the DAC output. Keep pixel clock (SCLK) traces short and surrounded by digital ground to limit radiated EMI at HD pixel rates.
The 75 ohm transmission-line environment is mandatory for SD composite (CVBS) and HD component outputs. Mismatched impedance causes reflections that appear as ringing or level errors in the analog video signal. Per ADI application notes, place the 75 ohm termination at the connector end of the trace, not at the IC pin, to maximize signal integrity for SD output modes.
Estimated: at AVDD = 3.3 V, full HD component output into 75 ohm loads, total supply current is roughly 100 mA (3 DACs active), giving approximately 330 mW dissipation. The 40-LFCSP-VQ (6x6 mm) exposed-pad package dissipates this comfortably without a heatsink at +25 °C ambient, but at +85 °C ambient with no airflow, validate junction temperature via the IC's theta_JA on your board to stay below 125 °C.
Per ADI documentation, do not leave any of the DAC output pins floating even if unused - tie them to AGND through their RSET-style termination to prevent current-source saturation. Do not drive digital video inputs before DVDD is stable; the ADV7393's PLL may not lock if pixel data arrives during power-up. Always issue a software reset via the I²C reset register after power stabilizes before configuring output modes.
合规信息
