952926CGLF

Application Specific Clock/Timing Overview

The IDT 952926CGLF is a 48-pin clock generator belonging to the Timing Control Hub (TCH) family, designed for VIA VX/CX 700 style chipsets. It operates with a fanout DDR buffer, such as the 93788, to provide necessary system clocks. The device features a serially programmable I2C interface allowing configuration of frequency settings, output divider ratios, spread spectrum percentages, output skew, and strength. M/N control enables output frequency adjustment with 0.1MHz resolution.

Application Specific Clock/Timing Feature Summary

• Serially programmable via I2C interface for flexible clock configuration
• Supports M/N control with 0.1MHz frequency resolution
• Configurable output skew, strength, and spread spectrum modulation
• Compatible with VIA VX/CX 700 chipset architectures

Application Specific Clock/Timing Applications

• VIA VX/CX 700 style chipset systems
• DDR memory subsystem clock generation
• System timing control hubs

Application Specific Clock/Timing Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm package integrity and pin alignment against the 48-pin specification. Check manufacturing date codes for potential obsolescence or lifecycle changes. Ensure compatibility with required I2C addressing and voltage levels before integration into design.

Application Specific Clock/Timing Selection Notes

Select this component when designing for VIA VX/CX 700 class chipsets requiring precise clock synchronization. Verify that the system architecture supports I2C programming for dynamic clock adjustments. Ensure the design includes a compatible fanout DDR buffer like the 93788 to handle signal distribution requirements effectively.

Application Specific Clock/Timing Part Context

The 952926CGLF is part of IDT's TCH line of clock generators and buffers. It utilizes advanced clock technology for robust functionality in desktop and workstation platforms. The CGLF suffix indicates a lead-free, RoHS-compliant variant in a specific 48-pin package format suitable for surface mount assembly.

Application Specific Clock/Timing Replacement Considerations

Direct replacements are limited due to proprietary I2C programming registers. Evaluate other TCH series devices from IDT/Renesas if functional equivalence is required. Verify pin-to-pin compatibility and software register mapping before substituting.
