ISL98003INZ-110

Analog Front End (AFE) Overview

The ISL98003INZ-110 is an 8-bit triple Analog Front End (AFE) designed to digitize analog YPbPr video from HDTV tuners, set-top boxes, SD/HD DVDs, and RGB graphics signals. It features a maximum conversion rate of 110MSPS, supporting resolutions up to UXGA at 60Hz. The device integrates a Digital PLL for pixel clock generation with low jitter, Automatic Black Level Compensation (ABLC), and precision sync timing measurement tools. Operating within a temperature range of -40°C to +85°C, it utilizes dual power supplies: 3.3V for analog/digital I/O and 1.8V for the digital core and ADC.

Analog Front End (AFE) Feature Summary

• Triple 8-bit ADCs with programmable oversampling up to 8x in video modes
• Digital PLL generates pixel clocks from 10MHz to 165MHz with 250ps peak-to-peak jitter
• Automatic Black Level Compensation (ABLC) eliminates part-to-part offset variation
• Integrated RGB to YUV color space converter and glitchless Macrovision-compliant sync separator

Analog Front End (AFE) Applications

• Flat Panel TVs
• Front/Rear Projection TVs
• PC LCD Monitors and Projectors
• High Quality Scan Converters
• Video/Graphics Processing

Analog Front End (AFE) Procurement Notes

Verify the specific suffix '-110' confirms the 110MSPS speed grade, as other variants like CNZ-165 offer higher rates. Confirm the 'INZ' designation indicates the industrial temperature range (-40°C to +85°C) versus the commercial 'CNZ' range. Ensure the package matches the 80-lead EPTQFP form factor specified in the ordering information.

Analog Front End (AFE) Selection Notes

Select this model when an industrial temperature rating is required alongside a 110MSPS sampling rate. Compare against ISL98003CNZ-110 if operating conditions are limited to 0°C to +70°C. Consider ISL98003CNZ-150 or -165 variants only if higher resolution support beyond UXGA at 60Hz is necessary. Verify power supply requirements for both 3.3V and 1.8V rails are met by the system design.

Analog Front End (AFE) Part Context

This component belongs to the Intersil (now Renesas) ISL98003 family of video AFEs. It shares the same 80-lead EPTQFP package and core architecture with the ISL98003CNZ series. The primary distinction lies in the guaranteed maximum conversion rate and the operational temperature range, with the INZ variant providing extended thermal capability compared to the standard commercial parts.

Analog Front End (AFE) Replacement Considerations

Direct functional replacements include ISL98003CNZ-110 for commercial temperature applications. For higher performance needs, ISL98003CNZ-150 or ISL98003CNZ-165 may be considered if the thermal envelope allows. No other pin-compatible models with different speed grades or temperature ratings are listed in the official documentation.
