IDTCV183-2BPAG

Overview

The IDTCV183-2BPAG is a programmable clock generator from the FlexPC series, designed for P4 processor platforms. It integrates four high-precision PLLs to generate CPU, SRC, SATA/PCI, and fixed frequency outputs. The device supports spread spectrum modulation and direct frequency programming via SMBus. Key specifications include a maximum output frequency of 400MHz, a supply voltage range of 3.135V to 3.465V, and operation within a commercial temperature range of 0°C to 70°C. It utilizes a 64-TSSOP package.

Feature Summary

• Compliant with Intel CK505 Gen II specification
• Four independent PLLs for CPU, SRC, SATA/PCI, and fixed frequencies
• Supports spread spectrum modulation (down and center spread)
• Direct CPU and SRC frequency programming via SMBus

Applications

• P4 Processor clock generation
• PCI Express (PCIe) systems
• SATA interface timing

Procurement Notes

Verify the specific ordering suffix 'B' against official Renesas documentation to confirm package type and revision status. Confirm that the required pin configuration modes (CFG pins) align with the target board design before procurement.

Selection Notes

Select this component when designing for P4 architecture requiring CK505 compliance. Ensure the system requires the specific output count of differential CPU/SRC pairs and single-ended PCI/USB clocks. Verify SMBus connectivity for frequency configuration needs.

Part Context

This part belongs to the IDTCV183-2 family of programmable clock generators. The 'BPAG' suffix typically denotes the specific package variant (TSSOP) and environmental rating. It serves as a central timing solution for legacy P4 chipset designs.

Replacement Considerations

Check for updated revisions or pin-compatible alternatives in the FlexPC series if availability is an issue. Ensure any substitute maintains the same 64-TSSOP footprint and electrical characteristics.
