MC44818DR2

Video Processing Overview

The MC44818DR2 is a video tuner integrated circuit manufactured by Motorola (NXP). It serves as a PLL frequency synthesizer for TV and VCR tuner applications, managing all functions required for Phase-Locked Loop control of a Voltage-Controlled Oscillator. The device supports I2C bus communication and operates within a voltage range of 4.5V to 5.5V. It is housed in a 16-pin SOIC surface-mount package.

Video Processing Feature Summary

• Integrates complete PLL control functions for VCO tuning on a single chip
• Supports I2C bus interface for digital configuration
• Designed specifically for TV and VCR tuner applications

Video Processing Applications

• TV tuner circuits
• VCR tuner circuits
• PLL frequency synthesis systems

Video Processing Procurement Notes

Verify the manufacturer origin, as production may have transitioned from Motorola to NXP or Freescale. Confirm the specific suffix 'DR2' corresponds to the standard SO-16 package variant. Ensure compatibility with existing I2C bus protocols in the target design. Check for RoHS compliance status if required by regional regulations.

Video Processing Selection Notes

Select this component when a dedicated tuner IC with integrated PLL control is required for analog video applications. It is suitable for designs needing I2C programmability for channel selection. Consider the 4.5V to 5.5V operating range and SO-16 package constraints during PCB layout.

Video Processing Part Context

This part belongs to the video processing category, specifically focusing on tuner control. It replaces older discrete PLL solutions by integrating VCO control logic. The DR2 suffix typically denotes the tape-and-reel packaging format for the SO-16 case.

Video Processing Replacement Considerations

Direct substitutes are not explicitly confirmed in public documentation. Evaluate other NXP video tuner ICs with similar I2C interfaces and PLL capabilities. Verify pinout compatibility before attempting any cross-reference.
