Analog Devices Inc. ADV7180WBST48Z

Overview

ADV7180WBST48Z from Analog Devices is an AEC-Q100 qualified automotive-grade SDTV video decoder that converts NTSC/PAL/SECAM composite, S-Video, and component analog video into 8-bit ITU-R BT.656 YCrCb 4:2:2 digital output. It features a 10-bit, 4× oversampling ADC for CVBS inputs, integrated 5-line adaptive comb filters, and supports −40°C to +85°C operation in a 48-lead LQFP package. Used in rearview camera systems and in-car infotainment units.

For engineers reviewing the ADV7180WBST48Z datasheet, ADV7180WBST48Z pinout, ADV7180WBST48Z application, or ADV7180WBST48Z equivalent, key selection criteria include automotive temperature qualification (−40°C to +85°C), 3-channel analog input support with on-chip antialiasing, Macrovision copy protection detection, and glueless interface capability to MPEG encoders and video processors via BT.656.

Technical Context

The ADV7180WBST48Z implements a monolithic 10-bit SDTV decoder with adaptive digital line length tracking (ADLLT™) for robust VCR and tuner signal handling, and includes dedicated circuitry for teletext (WST), closed captioning (CCAP), and CGMS-A data slicing. Its analog front end uses differential ADC channels with programmable clamping and AGC, supporting 1.0 Vpp input range across all three video input paths.

Internally, it integrates a PLL locked to a 28.6363 MHz crystal, generates line-locked LLC clock (nominally 27 MHz ±5% variation), and provides HS/VS/FIELD timing outputs alongside interrupt-driven status reporting via INTRQ. The 2-wire I²C interface enables full register configuration including pixel format (8-bit BT.656), chroma transient improvement (CTI), and digital noise reduction (DNR).

Key Specifications

Pinout & Package

ADV7180WBST48Z is housed in a 48-lead, 7 mm × 7 mm, RoHS-compliant LQFP package with exposed pad connected to ground. Thermal resistance is θJA = 50°C/W (still air, 4-layer PCB).

FAQ

What video standards does the ADV7180WBST48Z support?

The ADV7180WBST48Z supports worldwide NTSC (M/J, 4.43), PAL (B/D/I/G/H, 60, M, N, Nc), and SECAM (B/D/G/K/L) standards. It performs automatic detection and seamless switching between these formats without firmware intervention. All supported standards are processed through the same 10-bit ADC and adaptive comb filter pipeline within the ADV7180WBST48Z, ensuring consistent video quality regardless of input source.

Does the ADV7180WBST48Z require an external crystal?

Yes, the ADV7180WBST48Z requires a 28.6363 MHz fundamental crystal connected between XTAL and XTAL1 pins for PLL operation. The datasheet specifies ±50 ppm frequency stability and mandates use of a fundamental-mode crystal - not a third-overtone type. An external 1.8 V clock oscillator may be used instead, but the crystal configuration remains the default and validated reference for ADV7180WBST48Z timing accuracy.

Can the ADV7180WBST48Z decode teletext data?

Yes, the ADV7180WBST48Z includes a full-featured VBI data slicer with dedicated world standard teletext (WST) support. It extracts teletext pages from composite video signals and transmits them as ancillary data packets (ANC) on the 8-bit BT.656 output bus. This functionality is enabled by default and requires no additional configuration beyond standard ADV7180WBST48Z initialization sequences.

What is the power consumption of the ADV7180WBST48Z in active mode?

In active mode with CVBS input, the ADV7180WBST48Z draws 33–43 mA from AVDD, 77–85 mA from DVDD, 12–15 mA from PVDD, and 3–5 mA from DVDDIO - totaling approximately 125–148 mA at nominal 1.8 V supplies. Power-down mode reduces total current to ≤10 µA, making the ADV7180WBST48Z suitable for always-on automotive camera modules with wake-on-video capability.

Is the ADV7180WBST48Z pin-compatible with other ADV7180 variants?

No, the ADV7180WBST48Z is not pin-compatible with other ADV7180 package variants. Its 48-lead LQFP pinout differs from the 32-lead LFCSP, 40-lead LFCSP, and 64-lead LQFP versions - particularly in power pin distribution, GPO allocation, and timing signal placement. Board redesign is required when migrating between packages; the ADV7180WBST48Z pin configuration is documented in Figure 5 and Table 12 of the Rev. K datasheet.
