ISL98003CNZ-165

Analog Front End (AFE) Overview

The ISL98003CNZ-165 is an 8-bit video Analog Front End (AFE) manufactured by Renesas Electronics Corporation. It features three-channel analog-to-digital converters with a maximum conversion rate of 165MSPS, supporting resolutions up to UXGA at 60Hz. The device digitizes YPbPr and RGB signals using a Digital PLL for pixel clock generation with 250ps peak-to-peak jitter. Key specifications include programmable input bandwidth from 10MHz to 450MHz, ±6dB gain adjustment, and Automatic Black Level Compensation (ABLC). It operates on 3.3V and 1.8V supplies within a commercial temperature range of 0°C to +70°C.

Analog Front End (AFE) Feature Summary

• Triple 8-bit ADCs with oversampling capabilities up to 8x in video modes
• Integrated Digital PLL generating pixel clocks from 10MHz to 165MHz
• Automatic Black Level Compensation (ABLC) for offset elimination
• RGB to YUV color space converter with programmable gain and offset

Analog Front End (AFE) Applications

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

Analog Front End (AFE) Procurement Notes

Verify the specific suffix -165 confirms the 165MHz maximum conversion rate capability. Confirm the CNZ designation indicates the 0°C to +70°C commercial operating temperature range. Ensure the package matches the 80-lead EPTQFP specification. Check current product status as legacy components may have limited availability or end-of-life notices.

Analog Front End (AFE) Selection Notes

Select this component when high-speed digitization up to 165MSPS is required for UXGA resolution. Choose based on the need for integrated sync processing and ABLC to simplify host microcontroller tasks. Verify that the 3.3V and 1.8V dual-supply architecture fits the system power design. Consider the 80-lead QFP package constraints for PCB layout.

Analog Front End (AFE) Part Context

This part belongs to the ISL98003 family of video AFEs. Variants like the INZ-110 and CNZ-150 offer lower maximum conversion rates of 110MHz and 150MHz respectively. All variants share the same 80-lead EPTQFP package and core functionality, differing primarily in speed performance and operating temperature ranges.
