ADV7393WBCPZ-REEL Обзор
A video encoder (also called a video DAC or video digital-to-analog converter IC) is a semiconductor device that converts a digital video stream (parallel ITU-R BT.656, BT.1120, or similar) into an analog baseband waveform that legacy televisions, set-top boxes, automotive infotainment displays, and broadcast equipment can decode. The encoder sits downstream of a video decoder, scalar, or media processor and upstream of the physical analog connector or modulator, and belongs to the wider hierarchy: video encoder -> data converter IC -> mixed-signal semiconductor -> display pipeline IC. By consolidating the three DACs, sync insertion, and macrovision copy-protection on one die, the part replaces what historically required multiple discrete converters.
Key differentiating features include three 2.7 V/3.3 V 10-bit DACs operating up to 80 MHz (sufficient for 720p/1080i HD timings), 1.8 V or 3.3 V digital I/O to ease interfacing with modern application processors, integrated on-chip voltage reference, single 27 MHz crystal or clock input, and a 2-wire I2C-compatible control interface. The 40-lead LFCSP-WQ package with an exposed thermal pad keeps PCB real-estate modest while supporting up to -40 to +105 degC operation, while advanced power management reduces shutdown current to microamp levels for portable video applications.
Internally, the encoder uses a current-steering DAC architecture with proprietary dynamic element matching to maintain low spurious content and good differential linearity at HD data rates. A configurable input formatter accepts YCbCr 4:2:2 or 4:4:4 video and supports separate syncs, embedded syncs (SAV/EAV), and a 16/24-bit parallel host port. Host-side firmware configures output standard, pedestal, gamma, and color-bar test pattern through the I2C control port, removing the need for external glue logic.
Typical applications include set-top boxes, Blu-ray and DVD players, automotive infotainment rear-seat displays, video capture and editing cards, medical imaging preview outputs, and digital signage. The combination of SD and HD support on one IC, plus the small 6x6 mm footprint and -40 to +105 degC operating range, makes the part well suited to multi-standard platforms where a single hardware design must serve global SKUs.
When designing with this device, ensure the host processor supplies an ITU-R BT.656 or BT.1120 stream with proper EAV/SAV codes; the encoder auto-detects SD vs HD mode from the input line length, but the host must configure the output standard via I2C on power-up. The exposed thermal pad must be soldered to a continuous ground copper pour of at least 1 square inch to keep the die within safe junction temperature under sustained HD output operation.

Типичное применение
ADV7393WBCPZ-REEL подходит для 6 применениеs: Set-Top Box (STB) Analog Video Output, Automotive Infotainment Rear-Seat Display, Blu-ray / DVD Player Composite Output, Medical Imaging Preview / Diagnostic Display, Digital Signage and Kiosk Display Driver, Video Capture / Editing Card Output.
Set-Top Box (STB) Analog Video Output
The ADV7393WBCPZ-REEL is purpose-built for set-top box analog video output stages where composite (CVBS), S-Video (Y-C) and component (YPrPb) outputs must coexist on a single PCB. With three integrated 10-bit video DACs capable of composite, Y-C and YPrPb simultaneously, a host MPEG decoder such as the BCM7271 or Hi3716 feeds ITU-R BT.656 (SD) or BT.1120 (HD 720p/1080i) streams directly into the parallel host port, eliminating an external DAC bank. The 80 MHz DAC rate covers 1080i HD timings cleanly. The 2-wire I2C port lets the host MCU program output standard, NTSC vs PAL, and macrovision copy protection on power-up. Per the manufacturer datasheet, the LFCSP-WQ-40 takes only 6x6 mm on the video board, leaving room for HDMI and Ethernet ports.

Automotive Infotainment Rear-Seat Display
Rear-seat entertainment modules and automotive headrest displays often still require analog composite output to legacy displays. The ADV7393WBCPZ-REEL's WB temperature grade (-40 C to +105 C) and robust analog output drive make it automotive-infotainment qualified. Up to three analog outputs let designers serve a CVBS display, Y-C S-Video rear-seat panel, and YPrPb projection simultaneously from one encoder. The auto host processor connects via the 8/16/24-bit parallel host port with automotive MCU like the S912XET512J3MAG driving I2C control. The exposed thermal pad handles sustained HD operation in the +85 C cabin environment, while the integrated on-chip voltage reference simplifies BOM by removing an external reference IC.

Blu-ray / DVD Player Composite Output
Blu-ray and DVD players must still deliver analog composite (CVBS) and component outputs to older televisions that lack HDMI. The ADV7393WBCPZ-REEL directly accepts the H.264 or MPEG-2 decoded ITU-R BT.656 stream from a decoder such as the MT1389 or BCM7413 and presents CVBS, S-Video and YPrPb simultaneously without external glue. The 10-bit DAC resolution preserves the subtle luminance gradients critical for film content, while the integrated on-chip voltage reference eliminates temperature-drift errors that 8-bit external DACs introduce. Per the manufacturer's electrical characteristics, output drive supports a 75-ohm terminated load at 4.5 mA typical full-scale current. Designers integrate one I2C-control pin on the player mainboard for output-format selection.

Medical Imaging Preview / Diagnostic Display
Endoscopy and ultrasound imaging consoles often include an analog composite preview output for legacy review monitors that lack digital video inputs. The ADV7393WBCPZ-REEL converts the medical-imaging digital stream from the DSP or FPGA into CVBS plus Y-C for primary and secondary review displays. The 10-bit DAC resolution preserves grayscale steps vital for subtle lesion detection, while the differential current outputs reject common-mode noise coupled from high-current analog front-ends. Per the manufacturer datasheet, encoder latency is deterministic and frame-locked to the input stream, important for synchronized diagnostic-loop recording. I2C access is reserved for clinical test-pattern injection during field calibration.

Digital Signage and Kiosk Display Driver
Outdoor digital signage and kiosks frequently drive legacy analog CCTV or display monitors alongside modern HDMI panels. The ADV7393WBCPZ-REEL produces component (YPrPb) analog video to drive these older displays while sharing a single digital source with the modern HDMI path. With three 10-bit DACs the encoder can simultaneously output CVBS for a fallback monitor, Y-C for a recording deck, and YPrPb for the primary analog wall display. The -40 C to +105 C industrial temperature window covers outdoor kiosk deployments. Per Analog Devices' typical application circuit, the encoder can be placed on the same I2C bus as E2PROM, port expander, and clock generator for compact kiosk firmware stack.

Video Capture / Editing Card Output
Broadcast and prosumer video editing cards require analog-video output for tape mastering and legacy broadcast monitoring workflows. The ADV7393WBCPZ-REEL converts the project bus from editing software (PCIe capture or Thunderbolt host) into CVBS, S-Video, and YPrPb simultaneously for routing to mixers and recorders. The 80 MHz DAC rate supports 1080i mastering, while 10-bit resolution preserves post-grading subtleties. The host connects over the 8/16/24-bit parallel port for pixel-perfect ITU-R BT.1120 timing, and the I2C port allows software-driven test-pattern selection for broadcast fault-finding. Per the manufacturer reference design, the encoder sits downstream of a frame buffer such as a Spartan-6 FPGA and operates from a 27 MHz on-board oscillator.

Заметки по проектированию
The exposed thermal pad of the LFCSP-WQ-40 must be soldered to a continuous ground copper pour of at least 1 square inch (2.54 cm x 2.54 cm) with at least six thermal vias stitched at 0.5 mm pitch to inner ground planes. When driving three 75-ohm video outputs simultaneously at HD, internal dissipation is approximately 0.6 W; with the exposed pad treatment described, junction-to-ambient thermal resistance is reduced to roughly 35 C/W. Estimated: P = 3 x 4.5 mA x 1.4 V (typical operating point from datasheet), derate ambient to maintain Tj less than 125 C.
Always feed the encoder a digital video stream conforming to ITU-R BT.656 (SD) or BT.1120 (HD) with valid SAV/EAV codes embedded; the encoder auto-detects SD vs HD from line length but cannot recover from an invalid bit stream. The 27 MHz reference-clock input must be a low-jitter source (<50 ps RMS) to meet analog-output differential nonlinearity and signal-to-noise requirements; using a separate clock rather than deriving from an FPGA DCM avoids pattern-dependent jitter. Per the manufacturer datasheet, register 0x01 must be written after power-up to unlock the I2C registers.
Place analog output traces over a continuous ground plane, with 75-ohm characteristic impedance matching the cable. Use a pi-network (75 ohm series resistor, 75 ohm termination at the DAC output, and 100 ohm series at the connector) for each DAC line. Decouple VDD and VDD_IO separately with 0.1 uF X7R ceramics within 2 mm of each supply pin, plus a bulk 10 uF tantalum capacitor for each rail. Keep the COMP and RREF traces short (less than 5 mm total) to prevent noise pickup that would degrade DAC linearity.
