CDCR83ADBQG4

Application Specific Clock/Timing Overview

The CDCR83ADBQG4 is a Direct Rambus Clock Generator manufactured by Texas Instruments, designed for memory and RDRAM clock frequency generation. It operates as an application-specific clock/timing IC with a maximum input frequency of 240 MHz and a minimum input frequency of 12.5 MHz. The device supports an output frequency range up to 280 MHz and functions as a clock buffer/driver with TTL input compatibility. It requires a supply voltage between 3 V and 3.6 V. The component is housed in a 24-SSOP package (0.154 inch / 3.90 mm width) and is rated for operation within a temperature range of -40°C to +85°C.

Application Specific Clock/Timing Feature Summary

• Designed specifically for Direct Rambus applications and memory clock frequency generation
• Integrates PLL functionality for precise clock signal multiplication and distribution
• Supports TTL input levels for direct interface with standard logic circuits

Application Specific Clock/Timing Applications

• Direct Rambus DRAM (RDRAM) systems
• High-speed memory controller interfaces
• Clock distribution networks requiring low jitter

Application Specific Clock/Timing Procurement Notes

Verify the complete part number including the G4 suffix, which indicates lead-free compliance, against the manufacturer's current datasheet. Confirm that the 24-SSOP package dimensions match the target PCB footprint requirements. Ensure the operating voltage range of 3V to 3.6V aligns with the system power supply specifications before procurement.

Application Specific Clock/Timing Selection Notes

Select this component when a dedicated clock generator for RDRAM or high-speed memory interfaces is required. It is suitable for designs needing a single circuit PLL-based multiplier/divider with TTL input compatibility. Consider the 24-SSOP package size and the specified temperature range if the application involves industrial or automotive environments.

Application Specific Clock/Timing Part Context

This component belongs to Texas Instruments' family of application-specific clock and timing integrated circuits. It serves as a specialized solution for generating stable clock signals for Direct Rambus memory architectures, distinguishing itself from general-purpose oscillators by its tailored design for high-frequency memory bus synchronization.
