Product details
Overview
ADV7182ABCPZ-RL from Analog Devices is a 10-bit SDTV video decoder IC with differential analog inputs, supporting NTSC/PAL/SECAM autodetection and converting CVBS, S-Video, and YPrPb signals into 8-bit ITU-R BT.656 YCbCr 4:2:2 output. It features a single 10-bit ADC with 4× oversampling, integrated 5-line adaptive comb filter, and Rovi copy protection detection. Designed for automotive infotainment systems requiring robust analog video decoding under harsh EMI conditions.
For engineers reviewing the ADV7182ABCPZ-RL datasheet, ADV7182ABCPZ-RL pinout, ADV7182ABCPZ-RL application, or ADV7182ABCPZ-RL equivalent, key selection criteria include differential input support up to 4 V common-mode range, −40°C to +105°C automotive temperature grade, I²C programmability, and BT.656-compliant 8-bit parallel pixel output with HS/VS/LLC timing signals.
Technical Context
The ADV7182ABCPZ-RL integrates a 4-channel analog front end with on-chip antialiasing filters and a differential-to-single-ended converter, enabling direct connection of differential CVBS without external amplifiers. Its standard definition processor (SDP) implements ADLLT™ line-length tracking and superadaptive 2D comb filtering for stable decoding of low-quality sources like VCRs and tuner outputs.
Video processing includes ACE (adaptive contrast enhancement), CTI (chroma transient improvement), DNR (digital noise reduction), and programmable AGC with adaptive peak white mode. The device uses a 28.63636 MHz crystal oscillator and delivers pixel data synchronized to LLC (line-locked clock), HS, and VS/FIELD signals - all compliant with LCD controller and ASIC interface requirements.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar SDTV video decoder applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADV7181BCPZ-RL | 9-bit ADC resolution; no Rovi detection; −40°C to +85°C industrial grade only. | Lacks automotive qualification and copy protection compliance - unsuitable for OEM head units. | Select only for cost-sensitive industrial monitors where Rovi and extended temperature are not required. |
| MAX9526ETM+ | 10-bit ADC but no differential input support; uses external reference; no ACE or ADLLT algorithms. | Requires external op-amps for differential CVBS; limited noise resilience in automotive EMI environments. | Consider for consumer media players where board space and EMI immunity are less critical than BOM cost. |
Compared with ADV7182ABCPZ-RL, the ADV7181BCPZ-RL offers lower resolution and no automotive qualification, while the MAX9526ETM+ lacks integrated differential front-end and advanced video enhancement - making ADV7182ABCPZ-RL the only option meeting full automotive AEC-Q100-aligned performance, noise rejection, and feature set requirements.
