Product details
Overview
ADV7391BCBZ-A-RL from Analog Devices is a low-power, 10-bit SD/HD video encoder in a 32-lead, 5 mm × 5 mm LFCSP package. It integrates three high-quality 10-bit DACs with programmable oversampling (16× for SD, 8× for ED, 4× for HD), supports composite, S-Video, and component YPrPb/RGB outputs, and delivers up to 37 mA DAC output current. It is used in portable media players and automotive infotainment systems requiring NTSC/PAL/720p/1080i analog video output.
For engineers reviewing the ADV7391BCBZ-A-RL datasheet, ADV7391BCBZ-A-RL pinout, ADV7391BCBZ-A-RL application, or ADV7391BCBZ-A-RL equivalent, key selection criteria include SD/ED/HD multiformat support, I²C-programmable luma/chroma filters, Macrovision Rev 7.1.L1/1.2 compliance, CGMS/WSS/closed captioning insertion, and content-dependent DAC power management for battery-constrained designs.
Technical Context
The ADV7391BCBZ-A-RL implements a fully integrated video timing generator with on-chip subcarrier locking, programmable VBI data insertion, and dual-data-rate (DDR) input support for HD formats. Its architecture includes separate adaptive sharpness and luma-SSAF filters, fully programmable YCrCb-to-RGB matrix, and gamma correction for precise color fidelity across NTSC, PAL, 720p, and 1080i standards.
It features patented content-dependent low-power DAC operation, automatic cable detection with DAC auto-power-down, individual DAC on/off control, and sleep mode consuming minimal quiescent current. The device accepts 8-bit SDR/DDR digital video inputs and operates from 1.8 V digital, 2.7–3.3 V analog, and 1.8/3.3 V I/O supplies across −40°C to +85°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| DAC resolution | 10-bit - ensures 1024-level grayscale and chroma precision for broadcast-compliant CVBS/Y-C/YPrPb output |
| Oversampling rate | 16× at 216 MHz (SD), 8× at 216 MHz (ED), 4× at 297 MHz (HD) - reduces aliasing and enables clean reconstruction filtering |
| Analog supply voltage | 2.7 V or 3.3 V - supports flexible system rail design while maintaining SMPTE/EBU output level compliance |
| Digital supply voltage | 1.8 V - minimizes dynamic power in portable applications without sacrificing timing margin |
| Operating temperature | −40°C to +85°C - qualified for industrial and consumer embedded video systems outside automotive grade |
| Video standards | SMPTE 274M (1080i), 296M (720p), 240M (1035i), EIA/CEA-861B, NTSC M/PAL B/D/G/H/I/M/N/60 - full SD/ED/HD baseband compatibility |
| Power management | Content-dependent DAC power-down, cable detection, sleep mode - reduces active power to <100 mW during idle or disconnected states |
Pinout & Package
ADV7391BCBZ-A-RL uses a 32-lead, 5 mm × 5 mm lead frame chip scale package (LFCSP) with exposed thermal pad. Pin functions are defined per the Rev. J datasheet Figure 19 and Table 15.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VAA | Analog supply | 2.7 V or 3.3 V analog power for DACs and analog output buffers; requires local 10 µF + 0.1 µF decoupling |
| VDD | Digital core supply | 1.8 V digital logic supply; powers register file, timing generator, and MPU interface |
| VDD_IO | I/O supply | 1.8 V or 3.3 V selectable for SCL/SDA/ALSB/SFL pins; sets logic threshold for I²C and control signals |
| PVDD | DAC power supply | 1.8 V supply dedicated to DAC core; isolated from digital noise to preserve SNR > 62 dB |
| RSET | DAC full-scale current reference | External resistor sets 37 mA max DAC output current; tolerance directly impacts CVBS amplitude accuracy |
| COMP | Internal PLL compensation | Connects external RC network to stabilize 16×/8×/4× oversampling PLL loop dynamics |
| SCL/SDA | I²C serial interface | Standard bidirectional I²C port (up to 400 kHz) for register configuration and status readback |
| CLKIN | Pixel clock input | Accepts 27 MHz (SD), 54 MHz (ED), or 74.25 MHz (HD); jitter tolerance ±2 ns ensures stable sync lock |
| HSYNC/VSYNC | External sync inputs | Supports both internal timing generation and external synchronization for genlock-capable systems |
| RESET | Hardware reset | Active-low asynchronous reset; initiates power-on sequence and clears all registers to default state |
Key Features
| Feature | Design Value |
|---|---|
| Programmable luma/chroma filters | Configurable filter responses (e.g., BT.601 vs. BT.709) enable precise standard-matching without external components |
| On-chip test pattern generator | Generates color bar, black bar, hatch, flat field, and gamma ramp patterns - eliminates need for external video source during debug |
| Macrovision and CGMS compliance | Rev 7.1.L1 (SD) and Rev 1.2 (ED) copy protection plus CGMS-A/B insertion - meets OEM content security requirements |
| Vertical blanking interval (VBI) insertion | Supports closed captioning (NTSC/PAL), wide screen signaling (WSS), and teletext - enables broadcast-ready output |
| Individual DAC on/off control | Per-DAC enable/disable allows dynamic output routing (e.g., disable Y-C DAC when using only RGB component) |
| Content-dependent DAC power-down | Reduces DAC current draw during static or low-motion frames - extends battery life in portable devices by up to 40% |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar video encoder applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADV7390BCBZ-RL | Same LFCSP-32 package and pinout; lacks ED/HD 8×/4× oversampling PLL - limited to SD-only (ITU-R BT.601/656, NTSC/PAL) operation | Targeted at cost-sensitive SD-only applications like basic DVD players; does not support 720p/1080i | Select ADV7390BCBZ-RL only if HD functionality is unnecessary and BOM cost reduction is critical |
| ADV7393BCPZ-RL | 40-lead LFCSP, 16-bit input port, 12-bit DACs, automotive-grade (−40°C to +105°C), adds RGB-to-YCrCb matrix and enhanced ED/HD filters | Required for automotive infotainment with AEC-Q100 qualification and 16-bit RGB input from image processors | Choose ADV7393BCPZ-RL when automotive qualification, wider input bus, or higher DAC resolution is mandatory |
Compared with ADV7391BCBZ-A-RL, ADV7390BCBZ-RL sacrifices HD capability for lower cost and power, while ADV7393BCPZ-RL adds automotive qualification, 16-bit interface, and 12-bit DACs at the expense of larger footprint and higher supply complexity.
