Analog Devices Inc. ADV7180KST48Z-RL

Overview

ADV7180KST48Z-RL from Analog Devices is a 10-bit, 4× oversampling SDTV video decoder IC 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 three analog input channels, integrated 5-line adaptive comb filters, Macrovision copy protection detection, and operates across −40°C to +85°C industrial/automotive temperature range.

For engineers reviewing the ADV7180KST48Z-RL datasheet, ADV7180KST48Z-RL pinout, ADV7180KST48Z-RL application, or ADV7180KST48Z-RL equivalent, key selection criteria include CVBS/Y/C/YPrPb input support, 28.6363 MHz crystal interface, 48-lead LQFP package with VS/FIELD multiplexed pin, and I²C-programmable video enhancement features for automotive infotainment and DVR systems.

Technical Context

The ADV7180KST48Z-RL implements a monolithic 10-bit ADC with 4× oversampling in CVBS mode and 2× oversampling in Y/C and YPrPb modes, synchronized to a 28.6363 MHz crystal. Its standard definition processor supports autodetection of PAL B/D/I/G/H/M/N/Nc, NTSC M/J/4.43, and SECAM B/D/G/K/L standards with adaptive digital line length tracking (ADLLT™) for VCR and tuner signal stabilization.

It delivers professional-grade video performance via integrated AGC with adaptive peak white mode, CTI/DNR enhancement, full VBI data slicing (WST teletext, CGMS, CCAP), and programmable 8-bit pixel port timing with HS/VS/FIELD outputs. The 48-lead LQFP package uses one pin for VS or FIELD selection, requiring software configuration per output format.

FAQ

What video standards does the ADV7180KST48Z-RL support?

The ADV7180KST48Z-RL supports worldwide NTSC (M/J/4.43), PAL (B/D/I/G/H/M/N/Nc), and SECAM (B/D/G/K/L) standards with automatic detection. It accepts CVBS, Y/C (S-Video), and YPrPb (component) analog inputs and outputs 8-bit ITU-R BT.656 YCrCb 4:2:2 data. This makes ADV7180KST48Z-RL suitable for global deployment in broadcast, automotive, and surveillance equipment without firmware reconfiguration.

Does ADV7180KST48Z-RL require an external crystal?

Yes, ADV7180KST48Z-RL requires a 28.6363 MHz fundamental crystal connected between XTAL and XTAL1 pins for PLL operation. The crystal must meet ±50 ppm frequency stability, and the recommended load capacitance is specified in the Analog Devices layout guidelines. An external 1.8 V clock oscillator may substitute the crystal, but the crystal solution is preferred for cost and jitter performance in ADV7180KST48Z-RL designs.

How is the VS/FIELD pin configured on ADV7180KST48Z-RL?

The VS/FIELD pin on ADV7180KST48Z-RL is multiplexed and configured via register 0x03[5:2] (OF_SEL[3:0]). In progressive mode, it outputs vertical sync (VS); in interlaced mode, it outputs field identification (FIELD). This dual-function design reduces pin count in the 48-lead LQFP package. ADV7180KST48Z-RL's default behavior after reset depends on detected video standard, but software control ensures precise timing alignment in custom video pipelines.

What power supply voltages does ADV7180KST48Z-RL require?

ADV7180KST48Z-RL requires four independent supplies: AVDD = 1.71–1.89 V (analog), DVDD = 1.65–2.0 V (digital core), PVDD = 1.65–2.0 V (PLL), and DVDDIO = 1.62–3.6 V (I/O). All can be supplied from a single 1.8 V source except DVDDIO, which may be 3.3 V to interface with legacy host processors. Proper decoupling (0.1 µF + 10 µF per supply) is mandatory per the ADV7180KST48Z-RL datasheet layout recommendations.

Is ADV7180KST48Z-RL qualified for automotive use?

ADV7180KST48Z-RL is rated for −40°C to +85°C industrial/automotive temperature grade and is AEC-Q100 qualified. However, its specific ordering option ADV7180WBST48Z-RL carries full AEC-Q100 Grade 2 certification (−40°C to +125°C) and enhanced reliability testing. For under-hood or high-ambient applications, ADV7180WBST48Z-RL is the certified automotive variant; ADV7180KST48Z-RL remains appropriate for cabin-mounted infotainment and rearview systems meeting the 85°C limit.
