Overview
The 841484DKILF is a FemtoClock crystal-to-differential clock generator by Renesas Electronics. It converts single-ended crystal inputs to low-voltage differential signaling (HCSL) outputs. The device operates at a core voltage of 3.3V and features a common architecture. Key jitter specifications include a typical RMS phase jitter of 0.16 ps, a maximum peak-to-peak cycle-to-cycle jitter of 36 ps, and a typical value of 15 ps. It is housed in a VFQFPN package with dimensions of 5.0 x 5.0 x 0.9 mm and a pitch of 0.5 mm.
Feature Summary
- Converts crystal oscillator signals to HCSL differential outputs
- Ultra-low RMS phase jitter performance for signal integrity
- Compact VFQFPN surface-mount packaging
Applications
- PCI Express clock generation
- High-speed digital interface synchronization
- Low-voltage differential signaling systems
Procurement Notes
Verify component authenticity through authorized channels due to potential counterfeit risks. Confirm RoHS compliance status via official documentation before integration. Check for moisture sensitivity handling requirements during storage and reflow processes. Ensure the specific suffix matches design specifications as ordering variations may exist without functional changes.
Selection Notes
Select this component when ultra-low jitter is critical for PCI Express or similar high-speed interfaces. The 3.3V core voltage compatibility simplifies power supply design. The small form factor suits space-constrained PCB layouts. Evaluate thermal dissipation needs given the dense package type.
Part Context
This part belongs to the FemtoClock family designed for precision timing applications. It addresses the need for clean clock distribution in modern high-speed digital systems where jitter tolerance is tight. The HCSL output standard ensures compatibility with various receiver inputs.
Replacement Considerations
No public confirmed substitute part numbers are available in the provided data.
