Overview
The 8T49N008A-050NLGI is a programmable clock generator from the FemtoClock NG series by Renesas Electronics. It features one PLL and eight LVPECL/LVDS outputs, supporting frequencies up to 300MHz. The device operates on a single 2.375V to 3.465V supply within a -40°C to +85°C temperature range. Packaged in a 48-VFQFN exposed pad, it accepts HCSL, LVDS, or LVPECL inputs. This component is designed for high-performance jitter attenuation and frequency synthesis in demanding digital systems.
Feature Summary
- Provides eight differential output channels with selectable LVPECL or LVDS signaling levels
- Integrates a fractional-feedback PLL for precise frequency translation and jitter cleaning
- Supports register programming via I2C interface for flexible configuration
Applications
- High-speed serial communication interfaces
- Network synchronization equipment
- Test and measurement instrumentation
Procurement Notes
Verify current availability status as this component may be subject to discontinuation notices. Confirm package markings and revision codes against official datasheets before integration. Ensure compliance with RoHS3 standards and check for any recent product change notifications affecting assembly sites or materials.
Selection Notes
Select this model when eight synchronized differential clocks are required from a single source. Verify input signal compatibility with supported HCSL, LVDS, or LVPECL formats. Ensure the application environment stays within the specified voltage and temperature limits for reliable operation.
Part Context
This part belongs to the FemtoClock NG family, engineered for low-jitter performance in datacom and telecom applications. It serves as a versatile clock synthesizer capable of generating multiple independent frequencies from a single reference input.
Replacement Considerations
Consult official substitution guides for compatible alternatives within the 8T49N008A series. Verify pinout and electrical parameter equivalence before replacing discontinued units.
