8V19N490-19BDGI

Overview

The 8V19N490-19BDGI is a FemtoClock NG jitter attenuator and clock synthesizer manufactured by Renesas Electronics. It provides 18 outputs with maximum frequencies up to 2.94912 GHz, supporting LVDS and LVPECL signaling levels for both inputs and outputs. The device accepts input frequencies up to 2 GHz and operates on a single 3.3 V power supply. Packaged in a CABGA-100 surface-mount format, it is designed for high-performance timing applications requiring low phase jitter and flexible clock distribution.

Feature Summary

• Generates up to 18 differential output signals simultaneously
• Supports LVDS and LVPECL input/output voltage standards
• Maximum output frequency capability of 2.94912 GHz
• Operates from a single 3.3 V power supply

Applications

• High-speed data communication systems
• Telecommunications infrastructure equipment
• Enterprise storage subsystems

Procurement Notes

Availability for the 8V19N490-19BDGI may be restricted or limited. Verification of current stock status and lead times should be conducted directly with authorized distributors or the manufacturer prior to procurement planning.

Selection Notes

Select this component when multiple low-jitter differential clocks are required from a single source. Ensure the design supports the 3.3 V supply rail and accommodates the CABGA-100 package footprint. Verify that the target application requires LVDS or LVPECL signaling compatibility.

Part Context

This part belongs to the 8V19N490A series within the FemtoClock product line. It functions as an integer clock synthesizer and jitter cleaner, distinct from fractional synthesizers or simple buffer devices found in other Renesas timing portfolios.

Replacement Considerations

Verify pinout and register compatibility before substituting with other FemtoClock NG parts. Cross-reference specific suffix codes to ensure identical electrical characteristics and packaging.
