CDCFR83ADBQR

Application Specific Clock/Timing Overview

The CDCFR83ADBQR is a Direct Rambus clock generator manufactured by Texas Instruments. It operates within a supply voltage range of 3V to 3.6V and supports input frequencies from 12.5MHz to 240MHz. The device generates an output frequency up to 280MHz, functioning as a zero-delay PLL clock multiplier. It is housed in a 24-SSOP package with a width of 3.90mm. The component is designed for surface mount installation and complies with RoHS standards.

Application Specific Clock/Timing Feature Summary

• Generates precise clock signals for Direct Rambus applications
• Integrates a phase-locked loop for low jitter performance
• Supports multiple input logic standards including HSTL, LVPECL, and LVTTL
• Provides differential outputs compatible with HSTL, LVDS, and SSTL

Application Specific Clock/Timing Applications

• Direct Rambus memory systems
• High-speed digital signal processing circuits
• Computer peripheral interface designs
• Data communication equipment requiring stable clock distribution

Application Specific Clock/Timing Procurement Notes

Verify the specific suffix 'ADBQR' corresponds to the 24-SSOP package and reel packaging configuration. Confirm that the operating temperature range meets the -40°C to +85°C requirement for the intended environment. Ensure compatibility with the required input voltage levels and check for any specific moisture sensitivity handling instructions during assembly.

Application Specific Clock/Timing Selection Notes

Select this component when a dedicated clock generator for Direct Rambus architectures is required. It is suitable for designs needing a single circuit to multiply or divide frequencies with minimal jitter. Consider the 24-SSOP footprint constraints and the need for differential output support when evaluating alternative clock sources within the Texas Instruments portfolio.

Application Specific Clock/Timing Part Context

This part belongs to the CDCF5801 family of zero-delay PLL clock multipliers. It shares functional similarities with other devices in the series but is specifically optimized for Rambus applications. The component integrates the necessary feedback loops to eliminate board-level delay effects, ensuring precise timing alignment between input and output clocks.

Application Specific Clock/Timing Replacement Considerations

The CDCF5801DBQR is listed as a direct substitute. Verify pinout compatibility and electrical specifications before substitution. No other public confirmed substitutes are identified in the provided documentation.
