8T49N006A-002NLGI8

Overview

The 8T49N006A-002NLGI8 is a programmable clock generator from the FemtoClock NG family, manufactured by Renesas Electronics Corporation. It operates within a supply voltage range of 2.375V to 3.465V and supports an operating temperature range of -40°C to +85°C. The device utilizes a crystal input and provides LVDS or LVPECL output interfaces. It is housed in a 32-VFQFN package with an exposed pad. This component functions as a frequency synthesizer designed for low-jitter clock generation applications.

Feature Summary

• FemtoClock NG PLL technology for low phase jitter performance
• Programmable via I2C interface for flexible configuration
• Supports LVDS and LVPECL output levels
• Operates on a single 2.5V or 3.3V power supply

Applications

• PCI Express (Gen1/Gen2) compliant systems
• Synchronous Ethernet line cards
• SONET/SDH network equipment
• Test and measurement instruments

Procurement Notes

Verify the specific ordering suffix against the official Renesas datasheet to confirm pinout and electrical characteristics. Confirm RoHS3 compliance status and check for Product Change Notifications regarding assembly site changes or material updates before procurement.

Selection Notes

Select this component when a low-jitter, programmable clock source with LVDS/LVPECL outputs is required. Ensure the design accommodates the 32-VFQFN thermal requirements. Verify that the I2C programming interface aligns with the system controller capabilities.

Part Context

This part belongs to the 8T49N006A series, which are crystal-to-frequency clock generators. The 'NLGI8' suffix typically denotes a tape-and-reel packaging format and specific lead finish or environmental compliance. It is distinct from the 8T49N004 and 8T49N008 models by its specific output count and internal divider configuration.

Replacement Considerations

Direct replacements may include other parts from the 8T49N006A family with different output configurations or frequencies. Cross-reference with the 8T49N004A or 8T49N008A series if output counts differ. Always verify register compatibility and pinout equivalence.
