840004BGI-01LF

Clock Generators, PLLs, Frequency Synthesizers Overview

The 840004BGI-01LF is a FemtoClock® clock generator and frequency synthesizer manufactured by Renesas Electronics Corporation. It operates with a maximum output frequency of 226.66 MHz and utilizes an internal Phase-Locked Loop (PLL) to generate stable clock signals from a crystal input. The device supports LVCMOS and LVTTL output types and functions within a supply voltage range of 3.135V to 3.465V. Designed for surface-mount installation, it is housed in an 8-TSSOP package with a width of 4.40mm. The component is rated for operation at temperatures between -30°C and +85°C.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific suffix '01' against official Renesas documentation to confirm pinout compatibility and electrical characteristics, as suffixes often denote package variations or temperature ranges. Ensure the source provides the complete datasheet for the 840004B series rather than generic family overviews. Confirm RoHS compliance status directly from the manufacturer's current product announcement or specification sheet prior to procurement.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when a fixed-frequency clock source near 226.66 MHz is required without external programming. Verify that the system power supply remains strictly within the 3.135V to 3.465V range to ensure proper operation. Check that the load capacitance requirements for the connected circuitry are compatible with the LVCMOS/LVTTL drive capabilities. Ensure the operating environment stays within the specified -30°C to +85°C commercial temperature grade.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This part belongs to the Renesas FemtoClock® series, which focuses on low-jitter clock generation solutions. It serves as a successor or alternative to earlier ICS clock generator families, offering integrated PLL functionality in small packages. The 840004B variant specifically targets applications requiring precise timing without the complexity of programmable multi-output synthesizers.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct replacements may include other 8-TSSOP clock generators from Renesas with similar frequency outputs, such as the 840001BGLF, provided the frequency and output logic match. Cross-vendor substitutes require verification of pin-to-pin compatibility and electrical parameter alignment.
