Analog Devices Inc. ADV7342BSTZ

Overview

ADV7342BSTZ from Analog Devices is a multiformat video encoder IC with six 11-bit, 297 MHz DACs supporting SD, ED, and HD analog outputs including CVBS, S-Video, YPrPb, and RGB. It operates across −40°C to +85°C, supports 74.25 MHz 24-bit HD input, SMPTE 274M/296M/240M compliance, and Macrovision Rev 7.1.L1 (SD) and Rev 1.2 (ED). It enables simultaneous SD and ED/HD operation in DVD recorders and Blu-ray players.

For engineers reviewing the ADV7342BSTZ datasheet, ADV7342BSTZ pinout, ADV7342BSTZ application, or ADV7342BSTZ equivalent, key selection criteria include DAC oversampling modes (16×/8×/4×), I²C programmability, dual data rate (DDR) input support, 3.3 V analog / 1.8 V digital supply architecture, and automotive qualification per AEC-Q100.

Technical Context

The ADV7342BSTZ integrates a complete on-chip video timing generator, subcarrier locking to external sources, and programmable YCrCb-to-RGB matrix conversion. Its six full-drive DACs deliver up to 37 mA output current with <2 ns skew between channels and 6–8 ns analog output delay, enabling direct connection to 75 Ω video loads without external buffering.

It supports three independent oversampling architectures: 16× at 216 MHz for SD, 8× at 216 MHz for ED, and 4× at 297 MHz for HD - each optimized for NTSC/PAL/720p/1080i/1035i standards. The device accepts 8-/16-/24-bit pixel data via SDR or DDR interfaces in YCrCb or RGB color spaces, with embedded EAV/SAV timing code handling and cable detection.

FAQ

What video standards does the ADV7342BSTZ support?

The ADV7342BSTZ supports NTSC M, PAL B/D/G/H/I/M/N, PAL 60, SMPTE 274M (1080i), 296M (720p), 240M (1035i), ITU-R BT.601/656, BT.1358, BT.1362, and BT.709-5. It handles interlaced and progressive formats from 480i to 1080p, with square-pixel modes at 24.54 MHz and 29.5 MHz. All standards are implemented in silicon - no firmware updates required for format switching.

Does ADV7342BSTZ require external output filtering?

No, the ADV7342BSTZ does not require external output filtering due to its integrated 16× (SD), 8× (ED), and 4× (HD) DAC oversampling architecture. Each mode generates a clean Nyquist-limited spectrum that meets SMPTE/EBU spectral mask requirements directly at the DAC output pins, enabling direct 75 Ω coaxial drive for CVBS, Y/C, YPrPb, and RGB signals.

How is Macrovision support implemented in ADV7342BSTZ?

The ADV7342BSTZ implements Macrovision Rev 7.1.L1 for SD formats and Rev 1.2 for ED formats in hardware - no external processor or license key required. It inserts compliant AGC pulses and sync suppression into the CVBS output stream under register control. This functionality is exclusive to ADV7342BSTZ; the pin-compatible ADV7343BSTZ omits Rev 7.1.L1.

What are the power supply requirements for ADV7342BSTZ?

The ADV7342BSTZ requires four independent supplies: VAA = 2.6–3.465 V (3.3 V nominal) for analog/DAC circuitry; VDD/PVDD = 1.71–1.89 V (1.8 V nominal) for digital core and pixel I/O; and VDD_IO = 1.71–3.63 V (configurable 1.8 V or 3.3 V) for control and data buffers. Sequencing is noncritical but recommended as VAA before digital rails.

Can ADV7342BSTZ operate in simultaneous SD and HD mode?

Yes, the ADV7342BSTZ supports true simultaneous SD and ED/HD operation - for example, generating CVBS (SD) and 720p YPrPb (HD) outputs concurrently from independent pixel streams. This is enabled by dual video pipelines, separate timing generators, and independent DAC banks - verified in Analog Devices' Rev.
