MC44817BDR2

Video Processing Overview

The MC44817BDR2 is a Phase-Locked Loop (PLL) frequency synthesizer integrated circuit manufactured by Motorola. Designed for digital tuning systems, it serves as a tuning circuit for TV and VCR tuner applications. The device integrates all functions required for PLL control of a Voltage-Controlled Oscillator (VCO) onto a single chip. It operates in a bipolar technology process and is housed in a 16-SOIC surface-mount package with a width of 3.90mm.

Video Processing Feature Summary

• Integrates complete PLL control functions for Voltage-Controlled Oscillators on a single chip
• Designed specifically for digital tuning systems in television and video cassette recorder tuners
• Utilizes bipolar semiconductor technology for signal processing

Video Processing Applications

• TV tuner circuits
• VCR tuner circuits
• Digital tuning systems requiring PLL VCO control

Video Processing Procurement Notes

Verify the component authenticity against Motorola specifications. Confirm the 16-SOIC package type and bipolar construction. Ensure the part matches the specific MC44817BDR2 designation for digital tuning applications. Check RoHS compliance status if environmental regulations apply to your assembly process.

Video Processing Selection Notes

Select this IC when a dedicated PLL controller for VCOs is needed in consumer video equipment. It is suitable for designs requiring integrated frequency synthesis without external complex logic. Consider the 16-SOIC footprint for surface-mount assembly constraints in compact TV or VCR chassis designs.

Video Processing Part Context

This component belongs to the MC44817 family of tuning circuits. The 'B' suffix typically denotes a specific revision or variant within the Motorola lineup. These parts were standard solutions for analog-to-digital transition in tuner electronics, providing stable frequency locking for RF stages in broadcast reception devices.

Video Processing Replacement Considerations

Direct substitutes may include other MC44817 variants or compatible PLL synthesizers from the same manufacturer family. Verify pin compatibility and electrical characteristics before substitution. Cross-reference with official Motorola replacement guides for legacy components.
