ISL59920IRZ-T7

Video Processing Overview

The ISL59920IRZ-T7 is a triple analog video delay line integrated circuit manufactured by Renesas Electronics Corporation. It provides skew compensation between three high-speed signals, specifically designed to correct timing mismatches introduced by CAT-5 twisted pair transmission of analog video. The device features programmable delays adjustable in steps of 46.5ns per channel and utilizes a simple serial interface for configuration. It operates within a supply voltage range of 4.5V to 5.5V and supports video amplifier gain settings of x1 (0dB) or x2 (6dB). The component is housed in a 20-pin QFN package with dimensions of 5mm x 5mm.

Video Processing Feature Summary

• Provides skew compensation for three high-speed analog video signals transmitted over twisted pair cabling
• Features programmable delay adjustments on each channel via a simple serial interface
• Supports configurable video amplifier gain settings for back-termination applications

Video Processing Applications

• Compensating for signal skew in CAT-5 twisted pair analog video transmission
• RGB video signal processing systems requiring precise timing alignment
• Consumer circuit video ICs needing multi-channel delay management

Video Processing Procurement Notes

Verify the specific suffix T7 indicates tape and reel packaging when sourcing. Confirm the manufacturer is Renesas Electronics Corporation, formerly Intersil, as brand naming conventions may vary across legacy documentation. Ensure the 20-QFN package type matches the design requirements. Check for RoHS compliance status in current datasheets. Validate that the operating temperature range meets system specifications.

Video Processing Selection Notes

Select this component when precise analog video signal alignment is required across three channels. It is suitable for designs utilizing CAT-5 infrastructure where cable-induced skew must be corrected. Consider the serial interface complexity against available microcontroller resources. Evaluate the power consumption relative to system thermal constraints. Verify compatibility with existing video amplifier topologies requiring specific gain configurations.

Video Processing Part Context

This part belongs to the ISL5992x series of triple analog delay lines, which includes variants like the ISL59921, ISL59922, and ISL59923. These components share similar functionality but differ in specific delay step resolutions, such as 31ns or 30ns steps found in other series members. The series is targeted at consumer electronics and video processing applications requiring robust skew correction capabilities.
