8T49N004A-065NLGI

Overview

The 8T49N004A-065NLGI is a programmable clock generator from the FemtoClock NG series by Renesas Electronics Corporation. It features a single circuit with a 1:4 input-to-output ratio, converting crystal inputs to differential LVDS outputs. The device supports maximum frequencies up to 312.5MHz and operates on a supply voltage of 2.375V to 3.465V. It is housed in a 32-VFQFN package with an exposed pad, designed for surface mount installation within an operating temperature range of -40°C to 85°C.

Feature Summary

• Single-circuit architecture with 1:4 input-to-output ratio
• Differential LVDS output configuration
• Crystal input interface
• 32-VFQFN (5x5) package with exposed pad

Applications

• High-speed digital system clock distribution
• Data communication equipment timing
• Industrial control systems requiring low jitter

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS3 compliance and check for Product Change Notices regarding assembly site or labeling updates. Ensure storage conditions adhere to Moisture Sensitivity Level 3 standards to prevent damage prior to soldering.

Selection Notes

Select this model when a single PLL with four differential LVDS outputs is required. Verify that the target application frequency does not exceed 312.5MHz. Ensure the design accommodates the 32-VFQFN footprint and thermal requirements associated with the exposed pad. Confirm compatibility with crystal oscillator inputs rather than CMOS/LVPECL inputs.

Part Context

This component belongs to the 8T49N004 family, specifically the FemtoClock NG line known for low jitter performance. The '065' suffix typically denotes a specific factory pre-programmed frequency configuration. It serves as a fixed-frequency solution variant within the broader programmable clock generator portfolio.

Replacement Considerations

Direct substitutes include other 8T49N004A variants with matching LVDS outputs and similar pinouts, such as the 8T49N004A-056NLGI. Verify electrical parameters and package dimensions before substitution. Cross-reference with IDT-branded equivalents if applicable.
