9DML4493ANLGI

Overview

The Renesas 9DML4493ANLGI is a clock multiplexer featuring four differential outputs and two differential inputs. It operates with LP-HCSL output signaling and accepts HCSL input signals within a frequency range of 1 to 200 MHz. The device supports spread spectrum input for EMI reduction and consumes approximately 124 mW typ at 3.3V. Packaged in a compact 5.0 x 5.0 mm VFQFPN, it is designed for high-performance computing, servers, storage, networking, and accelerator applications.

Feature Summary

• Accelerators

Procurement Notes

Verify the specific suffix 'NLGI' against official Renesas documentation to confirm temperature range and packaging details. Ensure compatibility with system voltage requirements of 3.3V. Confirm lead-free status and RoHS compliance through current datasheets before procurement.

Selection Notes

Select this component when four differential LP-HCSL outputs are required from two HCSL sources. Verify that the 1-200 MHz frequency range meets system needs. Consider the 124 mW power consumption and 3.3V supply voltage constraints during thermal design.

Part Context

The 9DML4493 belongs to Renesas' PCIe clock mux family, supporting Gen 1–7 architectures. It provides flexible clock distribution for complex systems requiring multiple synchronized outputs from limited input sources.

Replacement Considerations

Consult official Renesas substitution guides for verified alternatives. Generic cross-model replacements may not match pinout or electrical specifications.
