ML6518CH

Overview

The ML6518CH is a PLL-based clock driver manufactured by Fairchild Semiconductor. It features eight true output channels with zero inverted outputs, designed for precise clock distribution in digital systems. The device is housed in a PQCC44 package, also identified as LCC-44, constructed from plastic materials. This component functions as a programmable adaptive clock manager within the PACMAN series, enabling flexible signal routing and timing control for high-speed applications requiring multiple synchronized clock domains.

Feature Summary

• Provides eight dedicated true logic outputs for simultaneous clock distribution
• Integrates phase-locked loop circuitry for stable frequency generation
• Utilizes a compact plastic quad flat no-lead (LCC) surface-mount package

Applications

• Digital signal processing systems requiring multi-domain clock synchronization
• Telecommunications infrastructure equipment
• High-performance computing boards

Procurement Notes

Verify manufacturer origin carefully, as this part number appears across multiple entities including Fairchild, Micro Linear, Qorvo, and Rochester Electronics. Confirm that the specific lot corresponds to the intended original manufacturer specifications. Ensure the PQCC44 package variant matches the design footprint requirements before finalizing procurement orders.

Selection Notes

Select this component when eight non-inverted clock outputs are required within a single integrated circuit. The LCC-44 package necessitates specific PCB layout considerations for thermal dissipation and solder joint integrity. Evaluate the PLL bandwidth requirements against system jitter specifications to ensure adequate performance for the target application speed.

Part Context

This device belongs to the ML6510 series of programmable clock drivers. It shares functional similarities with variants like the ML6510CQ-80 but may differ in specific electrical characteristics or packaging details depending on the manufacturing source. The series is widely recognized for its adaptability in complex timing architectures.

Replacement Considerations

Cross-reference with ML6510CQ-80 and ML6510CQ80 for potential pin-compatible alternatives. Verify compatibility with Qorvo and Micro Linear sourced versions, as these manufacturers have produced equivalent parts in the same package style.
