ADV7320KSTZ

Overview

The ADV7320KSTZ is a multiformat video encoder featuring six 12-bit NSV DACs and a 64-lead LQFP package. It supports simultaneous SD/HD or PS/SD inputs and outputs with oversampling up to 216 MHz. The device accepts HD formats including SMPTE 274M (1080i/p), SMPTE 296M (720p), and SMPTE 240M (1035i). ED formats include SMPTE 293M and ITU-R BT.1358/1362. SD input supports CCIR-656 4:2:2 parallel data. Outputs include YPrPb HDTV, RGB, composite NTSC/PAL, S-video, and component video. It operates on dual supplies of 2.5 V/3.3 V with an analog supply of 2.5 V.

Feature Summary

• Supports high-definition, enhanced definition, and standard definition video input and output formats simultaneously.
• Integrates six 12-bit noise-shaped video precision DACs for high-quality analog signal generation.
• Includes internal test pattern generators and programmable filters for sharpness, adaptive filtering, and gamma correction.
• Features built-in copy protection mechanisms such as Macrovision Rev 7.1.L1 and CGMS-A/WSS signaling.

Applications

• EVD (enhanced versatile disk) players
• High-end SD/PS DVD recorders and players
• SD/PS/HDTV display devices
• SD/HDTV set-top boxes
• Professional video systems

Procurement Notes

Verify the specific ordering suffix KSTZ against the manufacturer's current datasheet to confirm pinout compatibility and lead-free status. Ensure that the required 3040 Ω RSET resistors are included in the design for proper DAC biasing. Confirm that the PCB layout adheres to the recommended separation of analog and digital grounds to maintain signal integrity.

Selection Notes

Select the ADV7320 over the ADV7321 if Macrovision Rev 1.2 support for EDTV and Macrovision Rev 7.1.L1 for SD are required. Verify that the system requires simultaneous processing of different resolution inputs, as this chip supports concurrent SD and HD/PS streams. Check that the target application can accommodate the 64-lead LQFP package dimensions and thermal requirements.

Part Context

This component belongs to the Analog Devices ADV7320/ADV7321 family of multiformat video encoders. It is designed to replace older single-format encoders by handling multiple standards within a single monolithic chip. The device serves as a bridge between digital video sources and various analog display interfaces, consolidating functionality previously requiring multiple discrete components.

Replacement Considerations

The ADV7321 is the primary functional substitute within the same series, differing primarily in copy protection features. No other direct cross-manufacturer replacements are documented in the provided source material.
