9DML4493ANLGI8

Overview

The 9DML4493ANLGI8 is a clock generator manufactured by Renesas Electronics Corporation, designed for high-performance computing and networking applications. It features four differential outputs supporting LP-HCSL signaling with a frequency range of 1 to 200 MHz. The device accepts spread spectrum input signals and operates on a single supply voltage of 3.3V. Typical power consumption is 124 mW. It is housed in a 20-pin VFQFPN package measuring 5.0 x 5.0 x 0.9 mm.

Feature Summary

• Four differential outputs utilizing LP-HCSL signaling
• Supports HCSL, LVPECL, LVDS, and LVCMOS input formats
• Accepts spread spectrum input for EMI reduction
• Operates at 3.3V with typical power consumption of 124 mW

Applications

• Servers
• Storage systems
• Networking equipment
• High-performance computing accelerators

Procurement Notes

Verify the specific suffix ANLGI8 against the manufacturer's official datasheet to confirm pinout, packaging dimensions, and RoHS compliance status. Ensure the ordering code matches the exact electrical specifications required for the target design, as suffixes may indicate variations in temperature grade or packaging type.

Selection Notes

Select this component when a low-power clock generator with four differential LP-HCSL outputs is required for PCIe or similar high-speed interfaces. Verify that the input signal format (HCSL, LVPECL, LVDS, or LVCMOS) is compatible with the source clock. Confirm that the 3.3V supply voltage aligns with the system power architecture.

Part Context

This part belongs to the 9DML series of clock multiplexers and generators from Renesas. It is distinct from other models in the family, such as the 9DML04, which shares similar output signaling but differs in input configuration and package size. The 9DML4493 is specifically optimized for applications requiring multiple differential outputs from a single reference.

Replacement Considerations

Direct replacements should be sought within the Renesas 9DML series. Verify compatibility regarding output count, signaling type (LP-HCSL), and package footprint (20-VFQFPN). Cross-referencing with the manufacturer's obsolescence notices is recommended.
