Overview
The 8T49N205A-004NLGI8 is a clock generator from the FemtoClock NG series manufactured by Renesas Electronics. It operates within a supply voltage range of 2.375V to 3.465V and supports an input frequency range of 8kHz to 125MHz. The device provides four LVPECL outputs with a maximum output frequency of 125MHz. It utilizes a single PLL architecture and features an I2C programming interface for configuration. The component is housed in a 32-VFQFN exposed pad package and is rated for operation between -40°C and 85°C.
Feature Summary
- Integrates low-phase noise PLL technology for precise clock generation
- Supports configurable differential LVPECL output levels
- Enables register programming via standard I2C serial interface
Applications
- High-speed data communication systems
- Network infrastructure equipment
- Test and measurement instruments
Procurement Notes
Verify the specific ordering suffix against official documentation to confirm pinout, packaging, and factory pre-programming settings. Confirm current availability status as product lifecycles may change. Ensure compatibility with system power supply voltages and I2C bus requirements before integration.
Selection Notes
Select this component when a single PLL solution with four LVPECL outputs is required. Verify that the target application frequency falls within the supported 125MHz limit. Ensure the design accommodates the 32-VFQFN thermal pad requirements for proper heat dissipation during operation.
Part Context
This part belongs to the FemtoClock NG family, designed for applications requiring low jitter performance. The 8T49N205A variant specifically targets scenarios needing multiple differential outputs derived from a single reference source. It serves as a replacement for legacy clock synthesizers in modern high-speed digital designs.
Replacement Considerations
Consult official substitution guides for compatible alternatives within the FemtoClock portfolio. Verify pin-to-pin compatibility and electrical parameter alignment before replacing existing components in production hardware.
