952906BGLF

Application Specific Clock/Timing Overview

The Renesas 952906BGLF is a clock generator within the Timing Control Hub (TCH) family, designed for PC main clock applications. It features 19 outputs with a maximum output frequency of 66 MHz and supports input frequencies up to 14.318 MHz. The device operates on 2.5 V or 3.3 V power supplies with a working current of 350 mA. Packaged in a TSSOP-48 format, it functions within a temperature range of 0°C to +70°C.

Application Specific Clock/Timing Feature Summary

• Programmable via serial I2C interface for frequency, divider ratios, spread spectrum, skew, and strength adjustments.
• Supports M/N control configuration with output frequency resolution up to 0.1 MHz increments.
• Provides individual enable/disable capabilities for each of the 19 output clocks.

Application Specific Clock/Timing Applications

• PC main clock generation for VIA VN800/CN700/P4M800 style chipsets.
• System timing when used with fanout DDR buffers such as the IDT93788.

Application Specific Clock/Timing Procurement Notes

This component is listed as End-of-Life (EOL). Availability is restricted, and distributors may not stock this part number in all regions. Verification of current lifecycle status and alternative sourcing channels is required before procurement planning.

Application Specific Clock/Timing Selection Notes

Select this component for legacy P4 processor systems requiring specific TCH™ functionality. Ensure compatibility with the target chipset's clock requirements and verify that the 66 MHz maximum output frequency meets system specifications. Consider the TSSOP-48 package constraints during PCB layout.

Application Specific Clock/Timing Part Context

The 952906BGLF belongs to the IDT/Renesas Timing Control Hub line, representing an evolution in clock generator technology with enhanced programmability. It was primarily utilized in desktop computer architectures during the Pentium 4 era to manage complex multi-clock signal distributions.

Application Specific Clock/Timing Replacement Considerations

Due to the EOL status, direct substitutes are not explicitly confirmed in public documentation. Engineers should evaluate modern clock generators from the same manufacturer or compatible families that support similar I2C programming interfaces and output counts.
