ZL50018GAC

Overview

The ZL50018GAC is a telecommunications interface integrated circuit manufactured by Microchip Technology. It functions as a clock switch or jitter cleaner designed for high-performance networking applications. The device operates within a supply voltage range of 1.71V to 1.89V and draws a typical supply current of 165mA. It is housed in a 256-ball Ball Grid Array (BGA) package with dimensions of 17mm x 17mm. The component supports surface mount installation and is rated for an industrial operating temperature range from -40°C to +85°C. This specific part number represents the commercial grade variant of the ZL50018 family, providing precise clock signal management capabilities for telecom infrastructure.

Feature Summary

• Provides low-jitter clock distribution and switching for synchronous digital systems
• Integrates multiple clock outputs from a single input source
• Supports flexible frequency multiplication and division ratios
• Designed for high-reliability telecommunications equipment environments

Applications

• Synchronous Ethernet (SyncE) network nodes
• Time Division Multiplexing (TDM) transport equipment
• Base station synchronization units
• High-speed data converter clocking systems

Procurement Notes

Verify the exact suffix 'GAC' against official Microchip documentation to confirm it denotes the commercial temperature grade (-40°C to +85°C). Ensure the 256-BGA footprint matches your PCB design constraints. Cross-reference the datasheet revision date to ensure compatibility with current manufacturing standards. Confirm RoHS compliance status through the manufacturer's official product change notification records before finalizing procurement orders.

Selection Notes

Select the ZL50018GAC when a single-input, multi-output clock solution is required for telecom gear. Compare against the GAG suffix if industrial temperature ratings are needed. Evaluate power consumption requirements against the 165mA specification. Ensure the 17x17mm BGA package fits within the available board space. Verify that the 1.8V nominal supply voltage aligns with the system power architecture.

Part Context

The ZL50018 belongs to Microchip's Timberwolf series of clock generators and switches. This family is widely used in carrier-grade networking hardware. The GAC suffix specifically identifies the commercial temperature version. It complements other timing devices like the ZL380xx audio processors and ZL400xx synthesizers in comprehensive system designs. The component replaces older discrete clocking solutions with integrated programmable functionality.

Replacement Considerations

Direct pin-to-pin replacements may include the ZL50018GAG for industrial temperature ranges. Check for updated revisions such as ZL50018GACZ if lead-free packaging is required. Verify functional equivalence with newer Timberwolf series parts like the ZL50021 for enhanced features. Consult Microchip's obsolescence notices for long-term supply chain planning.
