AK8181G

Clock Buffers, Drivers Overview

The AK8181G is a clock fanout buffer and multiplexer manufactured by Asahi Kasei Microdevices/AKM. It features a 1:4 input-to-output ratio with LVCMOS or LVTTL inputs and LVDS differential outputs. The device supports a maximum frequency of 650 MHz and operates on a single supply voltage ranging from 3.135V to 3.465V. Packaged in a 20-TSSOP surface-mount case, it functions within an operating temperature range of -40°C to 85°C.

Clock Buffers, Drivers Feature Summary

• 1:4 Fanout Buffer (Distribution) and Multiplexer configuration
• LVCMOS/LVTTL input compatible with LVDS differential outputs
• Maximum operating frequency of 650 MHz
• Single supply voltage operation between 3.135V and 3.465V

Clock Buffers, Drivers Applications

• Clock distribution networks requiring signal buffering
• Multiplexing multiple clock sources into a single output path
• High-speed digital systems utilizing LVDS signaling standards

Clock Buffers, Drivers Procurement Notes

Verify the specific manufacturer part number against official Asahi Kasei Microdevices documentation to confirm current availability status. Ensure that the 20-TSSOP package dimensions match the target PCB footprint requirements. Confirm that the LVCMOS/LVTTL input levels are compatible with the source clock driver before integration.

Clock Buffers, Drivers Selection Notes

Select this component when a single-ended CMOS/TTL clock source needs to be distributed to four LVDS loads. The 650 MHz frequency rating suits high-speed data acquisition or communication interfaces. Verify that the power supply rail remains stable within the 3.135V to 3.465V window to maintain timing integrity across the operating temperature range.

Clock Buffers, Drivers Part Context

This component belongs to the AK8181 series of clock buffers and drivers. Other variants in the family include the AK8181A, AK8181B, and AK8181F, which differ in input/output ratios and supported input/output logic families. The AK8181G specifically addresses applications requiring one-to-four distribution with LVDS outputs.

Clock Buffers, Drivers Replacement Considerations

Check for direct pin-compatible substitutes within the AK8181 series, such as the AK8181B, if input compatibility allows. Verify that any replacement maintains the 650 MHz frequency capability and LVDS output characteristics required by the circuit design.
