9SQL4952BNLGI

Overview

The 9SQL4952BNLGI is a clock generator IC manufactured by Renesas Electronics Corporation, housed in a 24-VFQFPN package with an exposed pad. It features one circuit with differential outputs and supports input frequencies up to 100MHz. The device operates on a supply voltage ranging from 3.14V to 3.47V and functions within a temperature range of -40°C to 85°C. Primary applications include PCI Express systems.

Feature Summary

• Generates two 100MHz CPU/SRC outputs compliant with CK420BQ specifications
• Supports spread spectrum levels of 0%, -0.25%, or -0.5% for EMI minimization
• Includes a 25MHz LVCMOS REF output copy of the internal crystal oscillator
• Features integrated terminations for direct connection to 85Ω transmission lines

Applications

• PCI Express Gen 1/2/3 systems
• QPI and SMI interfaces
• SAS 12G compliant designs

Procurement Notes

Verify the component status as End-of-Life (EOL) through official manufacturer channels before procurement planning. Confirm that the specific ordering suffix 'NLGI' corresponds to the tray packaging variant listed in the datasheet, as alternative tape-and-reel options may exist.

Selection Notes

Select this component for designs requiring a CK420BQ derivative with low power consumption of approximately 112mW. Ensure the system architecture accommodates the 3.3V nominal supply voltage and utilizes the SMBus interface if software configuration of slew rates or output enables is required.

Part Context

This part belongs to the 9SQL4952 family, which are 2-output CK420BQ derivatives originally developed by Integrated Device Technology (IDT). Following corporate acquisitions, IDT products are now managed under the Renesas Electronics Corporation brand portfolio.
