Analog Devices Inc. ADV7340BSTZ

Overview

ADV7340BSTZ from Analog Devices is a multiformat video encoder IC with six 12-bit Noise Shaped Video® (NSV) DACs, supporting SD (16× oversampling at 216 MHz), ED (8× at 216 MHz), and HD (4× at 297 MHz) output generation. It delivers composite (CVBS), S-Video (Y-C), and component YPrPb/RGB analog outputs across NTSC, PAL, 720p, 1080i, and 1035i standards, and is used in DVD recorders and Blu-ray players for real-time digital-to-analog video conversion.

For engineers reviewing the ADV7340BSTZ datasheet, ADV7340BSTZ pinout, ADV7340BSTZ application, or ADV7340BSTZ equivalent, key selection criteria include its 74.25 MHz HD input support, SMPTE 274M/296M/240M compliance, Macrovision Rev 7.1.L1 (SD) and Rev 1.2 (ED), CGMS-A/B insertion, and simultaneous SD + ED/HD operation capability.

Technical Context

The ADV7340BSTZ implements a fully programmable video timing generator with integrated subcarrier locking to external video sources and on-chip test pattern generation. Its architecture supports dual data rate (DDR) and single data rate (SDR) pixel interfaces up to 30 bits, with independent YCrCb-to-RGB matrix conversion, gamma correction, and adaptive/sharpness filtering per format tier.

It features three full-drive DACs (DAC1–DAC3, 37 mA max) for CVBS/Y-C/component outputs and three low-drive DACs (DAC4–DAC6) optimized for RGB/component paths. Oversampling PLLs are dedicated per resolution class: 216 MHz for SD/ED, 297 MHz for HD, with precise analog output skew control (≤2 ns between DAC1–DAC3).

Key Specifications

Pinout & Package

The ADV7340BSTZ is housed in a 64-lead LQFP package (10 mm × 10 mm, 0.5 mm pitch) with exposed thermal pad (EP) for enhanced thermal dissipation in high-density video PCB layouts.

Equivalent & Alternatives

The following parts are listed as comparable options for similar multiformat video encoder applications.

Compared with ADV7340BSTZ, ADV7341BSTZ removes Macrovision but retains identical pinout, timing, and DAC performance - making it a drop-in alternative where copy protection is irrelevant. THS8200IPHP offers lower integration and resolution, requiring external timing ICs and filters for HD use cases, limiting its suitability to basic SD monitoring.

FAQ

What video standards does the ADV7340BSTZ support natively without external configuration?

The ADV7340BSTZ natively supports NTSC M, PAL B/D/G/H/I/M/N/60, ITU-R BT.601/656, BT.709-5, SMPTE 274M (1080i), 296M (720p), and 240M (1035i) via on-chip register settings. All standards are implemented in hardware - no external firmware or lookup tables are needed. The ADV7340BSTZ achieves this through dedicated video timing generators and programmable subcarrier oscillators that lock to each standard's exact line rate and field frequency.

How does the ADV7340BSTZ handle simultaneous SD and HD output generation?

The ADV7340BSTZ uses independent pixel pipelines and dual DAC banks to generate SD (e.g., CVBS at 27 MHz) and HD (e.g., YPrPb at 74.25 MHz) outputs concurrently. Its internal timing generator allocates separate clock domains and oversampling PLLs - 216 MHz for SD/ED and 297 MHz for HD - ensuring zero timing conflict. This allows the ADV7340BSTZ to drive legacy composite monitors and modern HD displays from a single chip without external multiplexers or frame buffers.

What is the function of the RSET pin on the ADV7340BSTZ, and how does it affect DAC output?

The RSET pin on the ADV7340BSTZ sets full-scale output current for all six DACs via an external resistor. A 510 Ω resistor yields 37 mA (full-drive mode for CVBS/Y-C), while 4.12 kΩ yields 4.5 mA (low-drive mode for RGB/component). This directly determines output voltage swing into 75 Ω loads: 37 mA → 2.775 Vpp, 4.5 mA → 0.3375 Vpp. The ADV7340BSTZ datasheet specifies RSET tolerance impact on gain matching (±1.0% DAC-to-DAC), making resistor selection critical for multi-channel amplitude uniformity.

Does the ADV7340BSTZ require external filtering on its analog outputs?

No, the ADV7340BSTZ does not require external reconstruction filtering due to its integrated 16× (SD), 8× (ED), or 4× (HD) oversampling architecture. Each DAC uses a noise-shaped interpolation filter followed by a 216 MHz or 297 MHz reconstruction stage, pushing image aliases beyond 100 MHz - well above the 5.75 MHz (NTSC) or 5.5 MHz (PAL) baseband bandwidth. This allows direct connection to 75 Ω coaxial cables, as confirmed by ADV7340BSTZ evaluation board measurements showing <−60 dBc out-of-band energy.

Can the ADV7340BSTZ be configured for RGB output only, without YCrCb processing?

Yes, the ADV7340BSTZ supports native RGB input and output without YCrCb conversion. When RGB data is presented on the Y/C/S bus (with appropriate control register settings), the chip bypasses the YCrCb-to-RGB matrix and routes pixels directly to DACs 4–6 for RGB component output. This mode preserves full 12-bit RGB fidelity and avoids chroma subsampling artifacts - essential for PC graphics, medical imaging, and RGB-only display interfaces using the ADV7340BSTZ.
