ASM2I9940LG-32LT

Clock Buffers, Drivers Overview

The ASM2I9940LG-32LT is a fanout buffer distributed by onsemi, designed for clock signal distribution. It features a 2:18 input-to-output ratio and supports LVCMOS and LVPECL inputs with LVCMOS outputs. The device operates at a maximum frequency of 250 MHz within a supply voltage range of 2.375V to 3.465V. It is housed in a 32-LQFP package (7x7 mm) and functions reliably across an operating temperature range of -40°C to 85°C.

Clock Buffers, Drivers Feature Summary

• 2:18 Fanout Buffer topology
• Supports LVCMOS and LVPECL inputs
• Maximum frequency of 250 MHz
• Supply voltage range: 2.375V ~ 3.465V

Clock Buffers, Drivers Applications

• Clock distribution networks
• LVPECL to LVCMOS translation
• High-speed digital systems requiring signal buffering

Clock Buffers, Drivers Procurement Notes

Verify the specific ordering suffix 'L' against official documentation to confirm tray packaging details. Ensure the 32-LQFP (7x7 mm) footprint matches the target PCB design. Confirm that the 2.375V to 3.465V supply voltage aligns with system power rails before procurement.

Clock Buffers, Drivers Selection Notes

Select this component when a single differential or single-ended clock source needs to drive up to 18 LVCMOS loads. Verify compatibility between the source impedance and the LVPECL/LVCMOS input requirements. Ensure the 250 MHz speed meets the system timing constraints.

Clock Buffers, Drivers Part Context

This part belongs to the clock buffer category, specifically functioning as a fanout buffer. It serves as a signal conditioning and distribution element within larger electronic assemblies, bridging high-speed logic families like LVPECL to standard LVCMOS interfaces.

Clock Buffers, Drivers Replacement Considerations

Check for direct pin-compatible alternatives from onsemi or other manufacturers offering similar 2:18 ratios and 32-LQFP packages. Verify electrical parameter equivalence, particularly the 250 MHz frequency limit and supply voltage ranges.
