Product details
Overview
ADV7390BCPZ 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, 4× for HD), supports composite (CVBS), S-Video (Y-C), and component YPrPb/RGB outputs, and delivers up to 37 mA DAC output current. It is designed for portable media players and digital camcorders requiring TV-out functionality with SMPTE 274M/296M/240M compliance.
For engineers reviewing the ADV7390BCPZ datasheet, ADV7390BCPZ pinout, ADV7390BCPZ application, or ADV7390BCPZ equivalent, this page provides verified technical context, validated pin functions, confirmed SD/ED/HD format support, real-world power management behavior, and direct alternative options for video encoder selection in space-constrained, battery-powered systems.
Technical Context
The ADV7390BCPZ implements a fully integrated video timing generator with subcarrier locking to external video sources, enabling precise NTSC/PAL synchronization without external crystal. Its programmable luma/chroma filters, gamma correction, and adaptive sharpness control operate independently per resolution mode-SD, ED, or HD-using dedicated oversampling PLLs (16× at 216 MHz for SD, 4× at 297 MHz for HD).
It features content-dependent DAC power management: automatic cable detection triggers DAC power-down on open-circuit, individual DAC on/off control enables selective output activation, and sleep mode reduces total supply current to minimal levels. The 8-bit parallel input supports both SDR and DDR interfaces, with full EIA/CEA-861B and SMPTE 274M/296M/240M compliance for 720p, 1080i, and 1035i formats.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| DAC resolution | 10-bit - ensures 1024-level grayscale fidelity and accurate color reproduction in CVBS/S-Video/component outputs |
| Oversampling rate (SD) | 16× at 216 MHz - suppresses imaging artifacts and relaxes anti-alias filter requirements for NTSC/PAL outputs |
| Oversampling rate (HD) | 4× at 297 MHz - meets SMPTE 274M/296M jitter and SNR requirements for 720p/1080i YPrPb signals |
| DAC output current | 37 mA max - drives standard 75 Ω video loads directly without external buffers in CVBS/Y-C configurations |
| Input interface | 8-bit SDR/DDR - supports ITU-R BT.656 embedded sync and external HSYNC/VSYNC for flexible system integration |
| Power supply | 1.8 V digital (VDD/PVDD), 2.7–3.3 V analog (VAA), 1.8/3.3 V I/O (VDD_IO) - enables dual-voltage domain optimization for low-noise analog and low-power digital operation |

| SCL/SDA | I²C interface | Standard-mode (100 kHz) and fast-mode (400 kHz) compatible; used for register configuration and status readback |
| RSET | DAC reference resistor | External 10 kΩ resistor sets full-scale DAC output current; enables precise output level calibration |
| RESET | Hardware reset | Active-low asynchronous reset; initializes internal registers and disables DAC outputs until deasserted |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar video encoder applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADV7391BCPZ | Same 32-lead LFCSP package and pinout; differs only in factory-programmed default register settings for ED/HD timing initialization | Preconfigured for enhanced definition (525p/625p) startup sequence; identical SD/HD functional capability and electrical specs | Select ADV7391BCPZ when ED timing boot behavior is preferred; no PCB or firmware changes required versus ADV7390BCPZ |
| ADV7392BCPZ | 40-lead LFCSP, 16-bit input port, 12-bit DACs; higher resolution input support and increased oversampling flexibility but larger footprint | Targeted at RGB input sources (e.g., graphics processors) and applications requiring >8-bit color depth or dual-format simultaneous output | Choose ADV7392BCPZ only if 16-bit input bandwidth or 12-bit DAC linearity is mandatory; not drop-in compatible due to pin count and package size |
Compared with ADV7391BCPZ, the ADV7390BCPZ offers identical hardware functionality but defaults to SD-first initialization-making it optimal for NTSC/PAL-centric designs. Against ADV7392BCPZ, ADV7390BCPZ trades input bandwidth and DAC resolution for smaller size and lower power, better fitting portable devices with 8-bit video pipelines.

FAQ
What video standards does the ADV7390BCPZ support natively?
The ADV7390BCPZ natively supports NTSC M, PAL B/D/G/H/I/M/N, PAL 60, SMPTE 274M (1080i), SMPTE 296M (720p), SMPTE 240M (1035i), and EIA/CEA-861B. It achieves this through on-chip subcarrier locking, programmable fSC generation, and format-specific oversampling-no external timing ICs or crystals are needed for standard-definition operation. The ADV7390BCPZ also handles square-pixel modes at 24.54 MHz and 29.5 MHz.
Does the ADV7390BCPZ require an external crystal oscillator?
No, the ADV7390BCPZ does not require an external crystal oscillator. It features integrated subcarrier frequency locking to external video sources (via HSYNC/VSYNC), enabling stable NTSC/PAL color burst generation without a crystal. For HD modes, it uses the incoming pixel clock (e.g., 74.25 MHz) directly-eliminating BOM cost and board space for timing components. The ADV7390BCPZ only needs a clean, low-jitter CLKIN signal meeting ±2 ns peak-to-peak jitter spec.
How does power management work in the ADV7390BCPZ?
The ADV7390BCPZ implements three-tiered power management: (1) automatic cable detection powers down unused DACs when no load is sensed; (2) individual DAC on/off control allows selective activation of CVBS, Y-C, or YPrPb paths; and (3) sleep mode reduces total current draw to minimal levels while preserving register state. This architecture enables typical operating current of 37 mA under full HD load, dropping significantly during idle or partial-output operation-critical for ADV7390BCPZ deployment in battery-powered devices.
Can the ADV7390BCPZ generate test patterns without external input?
Yes, the ADV7390BCPZ includes a fully integrated test pattern generator supporting color bar, black bar, hatch, and flat field/frame patterns-all configurable via I²C without any video input signal. These patterns are generated internally using the on-chip timing generator and DACs, making them ideal for production line calibration, field service diagnostics, and display compatibility verification. The ADV7390BCPZ test patterns cover SD, ED, and HD resolutions and can be synchronized to external sync signals.
Is the ADV7390BCPZ pin-compatible with other members of the ADV739x family?
The ADV7390BCPZ is pin-compatible with ADV7391BCPZ (same 32-lead LFCSP package and identical pinout), allowing direct substitution with only firmware register initialization differences. However, it is not pin-compatible with ADV7392BCPZ or ADV7393BCPZ, which use a 40-lead LFCSP package and differ in pin count, power pin allocation, and I/O configuration. Always verify package outline and thermal pad layout before board reuse.
