ADV7183BKSTZ

Overview

The ADV7183BKSTZ is a multiformat SDTV video decoder that converts NTSC, PAL, and SECAM analog baseband signals into digital ITU-R BT.656 YCrCb 4:2:2 data. It integrates three 10-bit ADCs clocked by a single 27 MHz crystal, supporting line-locked clock-compatible (LLC) output. The device features a 5-line adaptive comb filter, integrated AGC, and Macrovision detection. It accepts composite, S-Video, and component inputs via 12 analog channels. Power supplies include 3.3 V analog/I/O and 1.8 V digital core. It operates within 0°C to +70°C temperature range in an 80-lead LQFP package.

Feature Summary

• Integrates three 10-bit ADCs with fixed 54 MHz clocking for precise sampling
• Features a 5-line superadaptive 2D comb filter for superior chrominance separation
• Includes proprietary ADLLT algorithm to track varying video line lengths from poor quality sources
• Supports automatic NTSC/PAL/SECAM identification and standard definition processing

Applications

• DVD recorders
• Video projectors
• HDD-based PVRs/DVDRs
• LCD TVs
• Set-top boxes

Procurement Notes

Verify the specific suffix BKSTZ corresponds to the 0°C to +70°C commercial temperature grade as defined in the datasheet ordering guide. Confirm the package type is the 80-lead LQFP Pb-free variant. Ensure the source document explicitly lists this part number to avoid confusion with other temperature grades or pin-compatible models in the ADV7183 family.

Selection Notes

Select this component when a multiformat decoder supporting NTSC, PAL, and SECAM is required. It is suitable for applications needing line-locked clock outputs and mini-TBC functionality via ADLLT. Consider the 12-channel input muxing capability if multiple video sources must be managed. Verify power supply requirements match the 3.3 V analog and 1.8 V digital core specifications.

Part Context

The ADV7183B is part of Analog Devices' high-quality single-chip multiformat video decoder series. It is designed for professional and consumer applications requiring accurate conversion of analog baseband television signals. The device supports worldwide standards including NTSC-J/M/4.43 and various PAL and SECAM formats. It provides flexible digital output interfaces compatible with CCIR601/CCIR656 standards.

Replacement Considerations

Check for ADV7189BKSTZ for similar functionality with potential differences in channel count or resolution. Verify pin compatibility with ADV7180 or ADV7181 if space constraints require smaller packages like LQFP-48 or LFCSP.
